Fox pundits and conservative radio hosts like to complain about "political correctness" and the chilling effect it has on discourse contemporary society. There's no such thing, when Mel Gibson's movie can open at number one a few months after his drunken anti-semitic rave, and Gibson himself can march onto the Leno show to a rousing ovation.
Btw, I'm not buying the line that drinking is an excuse. Drinking might make you say things you wished you hadn't, sure. But drinking cannot form a thought in your head by itself. Gibson's belief that "Jews causes all the wars in the world" comes from belief system. Tequila didn't put it there.
So no more whining about the evils of political correctness please.
