/qa/ also had schizo posters just like /bant/, but how were they so different and why would one dislike one group and hate another, I'll explain...
/qa/ schizo posters did it for fun, to make others smile and laugh, they did it for everyone on board, it wasn't their entire personality.
/bant/ schizo posters do it for attention, they do it to get validation from their internet "friends", their entire personality revolves around being a "schizo" and want to be recognised as one.
Same can be said about nearly everything, even about /bant/ "jakkers". Just like redditors do things for upvotes and awards, /bant/ posters do it to get validation from their discord "friends". But in the end it doesn't matters how much attention they get, it won't make them a real woman. And no, sharing your thoughts isn't "seething", but ignoring facts and just insulting is.
