Redpill me on sageanon

Why does he go around posting "shitpost xDDDDDDDDDD" in every thread?

He can't accept the fact hes alone in his crusade against the shitposts. He needs to stand out and scream loud so the shitposters get the idea that his form of autism is superior to their own.
In futility he tries to sage threads on the front page. He doesn't know all the cool /prog/riders have gone and left him to decay in the shitpost culture. In desperate imitation of shitposters which he deceives himself is "just satire" he absorbs their culture and becomes one of them. The end.
