Because everyone here is a self-important little shit who thinks that other people should put up with them because they are so smart. You can extend that to the broader programming community.
Some of them probably do it defensively, preemptively driving people away because they can't deal with the feelings of rejection. Others just enjoy the ego boost. But most of them do it because it's accepted.
Anyway, these assholes are worth a lot less than they think.
Well, at least here on /prog/ we're occasionally creative with our self-important shitfuckery.

You specially.
And before you say anything, I'm venting my frustration over your shitty and disappointingly common attitudes you find here and everywhere else, not just being rude at the slightest opportunity.
