Alex enjoys our company because he'd rather be rejected by people he despise than by the people he admires.
To avoid repeats of the latter, he lives the life of a recluse and to enjoy the former, he hangs out on boards he has no interest in, insults as many people as he can in broad strokes, derails countless threads into topics he's the only one to care about and then he can be comforted that all who reject him are quarter educated morons with no taste, intellect or culture.
The human race will not miss him, he'll make sure of that.
