Today, (probably not saying this for the first time or the last here), as per thejadedhippy's example (Rainn Wilson in this case, I guess):
"O hai! I seem to have offended some people! Oh, look, lots and lots of people, now! All kinds of people! Many of them in groups considered marginalized! Some so marginalized I heretofore barely even tweaked their existence, except as a punchline! People are talking loudly and waving their hands in my general direction with angry faces! I am OFFENSIVE. Offensive means SPECIAL. I must be doing something right.
(Please note that the hoary phrase "politically correct" does not even need to be introduced at this juncture).
Basically, besides acting as a convenient cover for good ol' fashioned bigotry much of the time, this attitude is the American (among others, but especially) ideal of Bold Individualism** reduced and distilled until its most striking resemblance is to a puddle of dog piss on the carpet.
"Look! I marked my territory! Woof woof woof! Oh--people waving and making shouty noises. I think I might have done something Bad. Unfortunately I can't remember -why- it was bad, and they're still shouting. Meanwhile: hey, attention! Maybe bad is -good-! I don't like people being mad at me, but gosh, I -like- attention! Woof! Hey, they're shouting some more! This is kind of fun! BARK! BARK BARK BARK WOOF WOOF..."
Meanwhile, of course, the increasingly exasperated Wavy Shouty People alternate between ignoring, indulging, trying reward-discipline behavior and simply striking out with a rolled up newspaper when sufficiently aggravated.
No, I don't have any better ideas at this juncture either, I'm afraid. It'd be nice if non-canine people whose brains in reality probably -aren't- really the size of a walnut would stop acting that way, is all I know. Eh.
I mean, it's not that I don't even get the temptation to just, well, be an asshole. It's fun! It's easy! And it's the Amurrican Way!
What it -isn't- is particularly difficult or even entertaining most of the time. Most people aren't Lenny Bruce or even Dennis Leary. They're just, well? Assholes. We've all got 'em. Not uncommon, the asshole.
**I probably use this quote way too much, but:
But the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright Brothers. But they also laughed at Bozo the Clown.
Substitute "iconoclast" for "genius" and you pretty much have the mentality.
