Because it worked on them. At some point someone was a smug, obnoxious cunt to them online and they were like "Wow, thanks, I guess I'm a communist now!"
¯\_(ツ)_/¯ I sort of look at them as amusement. It's not like what they want will happen In our lifetimes (or ever probably). I don't necessarily get why everyone hates them, just try looking at them as funny content lol
They are the best example what happens when people are locked in their echo chamber. They are radicalizing themselves to the point of absurdity. The statements they make are so illogical its hard to even have a discussion about it, because they literally deny truisms.
I genuinely don't understand why the admins are dragging ass and not just defederating from them already. They provide nothing of value, just spam and harassment.
