I guess I should add that unlike those with autism they also would pick on kids less popular than them, spread fake rumors to make people pariahs and elevate their own social status comparatively, and call every act of unbridled enthusiasm by anyone "gay" as well.
That in itself is not bad, it is that in conjunction with bullying others to sustain the facade to yourself that you are cool that is bad. Everyone does it to some extent but people like Elon never grew out of it or did any self-searching to diffuse their need for self-consciously seeking strangers' approval.
