I've been there, but I mostly just do it anyway. Fuck it, I said what I said. Half the time you don't even get anything all that cutting, it's just png salad. Every now and then, you'll get a coherent response that isn't a death threat, and those end up being good reads more often than not.
Eh, more often than not their longer posts are just "actually Stalin/Putin/Mao/Kim dynasty/Trump good because <5 page essay>"
Edit: also the classic "comparing Stalin to Hitler is a form of Holocaust denial" and in the same breath calling everyone not in their vatnik bubble a nazi or fascist lmao
And of course, if you don't address every single point in that 5 page essay, along with doing all of their required reading, then you're clearly acting in bad faith and a shitlib and are now going to be dogpiled by 27 other Hexbear users.
Bro I had this commie from lemmy.ml post a meme advertising for how great communism was. And I told him how the state was authoritarian and basically didn't care much about human rights and the millions of people starving to death. I got wall of text and he got upset when I used wikipedia as a source. I'm sure if I used some news outlet he'd just say that's western propaganda so I ended up blocking the guy and later the instance.
