The prime problem is that every social space eventually becomes a circlejerk. Bots and astroturfing exacerbate the problem but it exists perfectly fine on its own – in the early 2000s I had the misfortune of running across plenty of gigantic, years-long circlejerks where definitely no bots or nefarious foreign manipulators were involved (I’m talking console wars, Harry Potter ship wars, stupid shit like that). People form circle jerks in the same way that salt form crystals. It’s just in their nature.

The thing with circlejerks isn’t that there’s overwhelming agreement on some subject. You’ll get dunked on in most any social media space for claiming that the earth is flat or that Putin is a swell guy, that in itself is obviously not a problem. What makes a circlejerk is that takes get cheered for and upvoted not in proportion to how much they are anchored in reality, but in proportion to how useful they are in galvanizing allies and disrupting enemies. Whoever shouts “glory to the cause” in the most compelling way gets all the oxygen. At that point the amount of brain rot is only going to increase. No matter how righteous the cause, inevitably there comes the point where you can go on the Righteous Cause Forum and post “2+2=5, therefore all glory to the cause” and get 400 upvotes.

Everyone talks a big game about how much they like truth, reason and moral consistency, but in the end when it’s just them and the upvote button and “do I stop and honestly examine this argument that gives me warm fuzzy feelings”, “is it really fair to dunk on Hated Group X by applying a standard I would never apply to anyone else” – the true colors show. It’s depressing and it makes most of social media into information silos where totalizing ideologies go to get validated, and if you feel alienated by this then clearly that space isn’t for you.
