Luckily, shedding light on the unique issues men face is not sexism. It is antisexism. Same for women.
- Comment on What even is fire? 3 days ago:
TL;DR Superheated products of burning in the state of plasma - essentially, an ionized gas.
Long answer:
*Boring part what causes the fire, you may skip it but it provides context
As is widely known, oxygen is the second most powerful elemental oxidizer in existence, second only to fluorine. Our atmosphere contains something like 21% of it, and nearly everything it could oxidize at our normal conditions it already did. We also use it to oxidize our food - for us, this is just breathing, but really it’s a complex set of reactions meant to essentially burn our food at low temperature.
However, one of the simplest thing that can be changed to make oxygen oxidize something else is temperature. Elevated temperatures lead to the weakening of the bonds between atoms in the molecule, making them more readily available for a chemical reaction. As a certain threshold called activation energy, the reaction (in this case rapid oxidizing, i.e. burning) starts to occur. From here on out, the heat provided by reaction is enough to heat the rest of material up to the energy required for reaction, and it becomes self-sustaining, heating further and further. The further the reaction heats up, though, the more heat it emits to the environment, and at some point, different for each fuel type and external conditions, heating and cooling of the reaction equalize at a certain temperature - typically about 600-1000°C (1100-1800°F).
Normally, when a chemical reaction occurs, bonds get so weak that atoms can leave the molecule and reconfigure in a different way - they don’t stay in this separate state for any significant time, and the outcome is always two molecules with swapped atoms. This is what happens inside our body in long chains of various reactions that involve oxygen. The end goal here is to extract as much energy as possible by putting electrons inside atoms in the most energy-efficient position, but that’s a topic for another time.
The thing is, fire works differently.
Now the part actually about the fire At such temperatures at which you see the flame, materials in the fuel don’t just swap atoms - they straight up break into free floating ions, or charged atoms, not bound to anything. They are so energized they rip chemical bonds apart. This state of matter is known as plasma, and it is very similar to gas, except gas consists of normal molecules and plasma is too hot to have that. So, in layman terms, you can see the flame as hot gas, though it wouldn’t be exactly correct.
Those ions then recombine into regular molecules, attempting to take the most energy-efficient configuration, and are moved out of the flame by the current s of air that itself gets expanded on heating. The products of this process are primarily carbon dioxide and water, as they are the most stable, energy-efficient bonds of carbon and hydrogen with oxygen, respectively.
As per why it glows - this is the property of its temperature. In fact, every object in the Universe that is above absolute zero temperature (0 degrees Kelvin, the lowest temperature there can be, signifying full stop in motion of any particles) emits electromagnetic radiation. The interactions of protons and electrons between particles form paired electric and magnetic fields. These fields radiate photons, and at the temperatures above about 500°C (950°F) the emitted electromagnetic radiation begins taking form of visible light. Due to the amounts of heated matter and the energies involved in the process, we see fire as a very bright light.
That’s it, in the nutshell :)

Feminism is driven primarily by, and meant primarily for, women. Men (and nonbinary people) can occasionally benefit from it, but they don’t commonly have a say in the way it develops.
Antisexism encompasses all people, and everyone has an equal voice as long as it calls for equality. It makes no sense to break it down to smaller units if everyone’s on the same page in that no one should be discriminated against. Men can be on the watch for cases of discrimination against women, and vice versa.
MRA (as in patriarchal men calling for male dominance and against feminism) are not welcome here. Coming from the men’s perspective, MRA may occasionally raise very real issues of men, which can cause the intersection of topics between them and the community; the problem is, many if not most of the MRA folks don’t want equality and also think of patriarchy as the magic pill to solve their issues, issues that are often caused by it in the first place.
You can look into men’s issues from the men’s perspective without encroaching on women’s rights in any way, shape or form, and this is one part of the multidirectional message the community tries to send.
The false dichotomy of “feminism or patriarchy” commonly leaves the opinions and unique struggles of non-patriarchal men out of the picture, and nonbinary people are straight up invisible in this conversation.
- Comment on Why I am not impressed by A.I. 5 days ago:
Here’s my guess:
We all know LLMs train on human-generated data. And when we ask something like “how many R’s” or “how many L’s” is in a given word, we don’t mean to count them all - we normally mean something like “how many consecutive letters there are, so I could spell it right”.
Yes, the word “strawberry” has 3 R’s. But what most people are interested in is whether it is “strawberry” or “strawbery”, and their “how many R’s” refers to this exactly, not the entire word.

It’s insane how much people are self-limiting with all those stereotypes. In my own relationship, I often help my loved one untangle a lot as well.

Happy to know I’m not the only one thinking this way!

Exactly! And I think being part of united community helps better understand the circumstances of others, which ends up helping everyone.
- Comment on !antisexism@lemmy.today - a joint movement of men, women and nonbinary people against all sorts of gender-based discrimination 1 week ago:
Yeah, unfortunately, in the later years the term has been widely used by a lot of bigots to push something very different from the original idea.
Even Wikipedia now mentions both.
en.wikipedia.org/wiki/Masculism
I only mean it in the original sense, and am happy that quite a few people agree that this community should have its place.

Masculism is a movement against gender-based discrimination of men.
It may take many forms, and, unfortunately, some of them are quite clearly misogynistic. Similarly, some forms of radical feminism may get misandric at times.
Those are not the flavors of feminism and masculism I talk about, and those are clearly against the community rules.
Among those feminists and masculists that call for true gender equality, however, contradictions are unnecessary since the end goal is exactly the same.
!mensliberation@lemmy.ca is:
- A community about men (!antisexism@lemmy.today is about everyone)
- Openly focused on the feminist perspective, which, in my opinion, is limited because it only takes one angle.
Think of !antisexism@lemmy.today as an attempt to form a wider group (men, women, and nonbinary) exploring gender inequality from different angles.

Then go and “blow shit up” - because right now you’re only blowing your ego out of proportion.
Going rough with commenters on the Internet is not struggle, it’s a parody.
- Comment on Norway on track to be first to go all-electric 4 weeks ago:
The Internet is now a mess of people screaming at each other - and so, did anything change for the better?
Conservative autocrats everywhere, environmental policy going to shitter - the progress we’ve made is reversing.
So, when you look in the mirror, ask yourself - do you really make the change? Or do you just sit and scream, much like everyone else?
- Comment on Norway on track to be first to go all-electric 4 weeks ago:
Maybe it’s time to realize insults won’t do anything to change someone’s opinion, while tanking the civility of a discussion.
Firmly with the mod on this one.

I feel like it’s a double-edged sword.
For as long as there are people willing to tip more, the company can get away spending less and shifting it onto customers.
As a result, workers get highly unpredictable and generaly low income and customers feel guilty for leaving low tips. Everybody but the company loses.

Thanks for provided context!
I’ll look into the data.
- Comment on flouride 2 months ago:
The question to me is - do we even have to fluoridate water and is this really the best approach?
For example, most European countries do not commonly use fluoride in their water supply, and everyone’s just fine! No extra cavities, no special health risks. People commonly drink tap water and do not care about potential for any adverse effects, because it’s just that - clean water. And for any teeth-related issues, you already have your toothpaste providing more than enough fluorine.

- Comment on Solar modules now selling for less than €0.06/W in Europe 2 months ago:
Sure, that’s what I threw in the “politically advantageous” bucket to not expand on it too much
- Comment on Solar modules now selling for less than €0.06/W in Europe 2 months ago:
So, in your mind this is a hidden lobbyist who tries to abuse “we destroyed local production” argument to make sure Europe slows down solar rollout and remains dependent on fossil for longer?
Not only is this too much of an effort to come from this angle, it’s also not a large platform to speak to.
Seeing an astroturfer in every person that has another angle on the issue is just plain paranoid, and at the same time makes you behave like an asshole towards others. This sort of behavior is what ruined many other platforms, with everyone yelling out of their echo chambers - angry, violent and utterly unproductive.
Algorithms have raised a generation of people doing what best engages them - shitting on each other. And when an alternative like Lemmy appears, where no algorithm is pushing anyone, people make the same mistakes. I urge you to break this chain, with compassion and care.

Do not assume bad faith over anything you disagree with.
While I disagree with the original statement, hostility never changed anyone’s mind.
