That's useless because all obnoxious people think of themselves as nice guys. No Hitler, Putin or Mao would say
: Yes, I'm a dick, a perv, a monster.
In the image they have of themselves, all a-holes are paragons of moral superiority and purity.

Dudeism uses the word "asshole" instead of dick but the meaning remains. Kurt Vonnegut Jr said, "Be kind." Many think that I don't achieve this standard because I don't engage prolonged argumentation (especially over what I've already written in reply to a question). It's hard to not be contentious when addressing a mass mistake of thought/behavior (especially when it's goal is of decent intention). People assume one is against the intention rather than their strategy for achieving it.

That's all it takes!
