First off

and you better believe that the comments going against their narrative are getting deleted on their instance

Is just a baseless accusation at this point.

Secondly if

Users from instances like hexbear, lemmygrad, exploding heads etc. seem to have some things in common: -Brigading -Trolling -Spreading misinformation/lies about genocides, wars, etc. -Demanding to be heard because of free speech and “tolerance” -When they face resistance, they get aggressive

were reported so often it’d be untenable the admins here would probably be more up in arms about it. Seeing as they are seeking open discussion about this issue, I’d defer to them in the assessment that the issue with comments of this kind is with individuals and not one of the instance.

Generally Propaganda is pretty much everywhere and everyone also is regurgitating some version of it, you or other liberal users will spew liberal propaganda, leftist will spew leftist propaganda, the Russian state spews Kremlin Propaganda, conservative Christians will spew conservative propaganda. You have it quite right in how that process happens.

But firstly, you me and everyone, can learn to recognize types of propaganda, and decide which propaganda to accept, and which to reject. Many people here are probably quite adept at this already, but I think the ones that look at the hexbar front page and see a united front of foreign propaganda have likely accepted a certain type of liberal propaganda, and reject much everything else as propaganda, and as such are not properly equipped for a more honest understanding about what the users there are saying.

To that point, I’m obviously spewing leftist propaganda by defending hexbear, but my argument can still be good, and you should be able to accept or reject it despite your biases, by trying to understand it.

And secondly ( and this is roughly following the admins thoughts as well ) liberalism it’s propaganda and followers are very common and in my view extremely destructive, sure not as destructive as conservatism or fascism would likely be, but definitely destructive enough to reject it in favor of leftist(communist, anarchist, socialist) ideology instead.

The large majority of (newer) lemmy users likely grew up under liberalism and so surrounded by it’s propaganda to accept it at least partially. This includes me, but throughout my life I’ve learned to reject a lot of liberal propaganda and accept different propaganda instead, because even though liberalism is so common it tends to explain and predict things less accurately and less completely, than socialist or anarchist theory does at least as far as I can see.
