He didn't really joke about any other ethnicity at the oscars apart from Asians though

No, he didn't. He didn't really have time for more than one joke, though. It was also an ad-lib that was spoken by a character known for being racially insensitive. But here's a racially charged joke that Chris Rock told that night which no one batted an eye at.

“But things are changing. We got a black Rocky this year … that’s a big statement because Rocky takes place in a world where white athletes are as good as black athletes. So Rocky is a science-fiction movie."

White and black stereotypes. That joke warranted absolutely zero outrage. Asians heard a few jokes at their expensive and ran to Twitter in righteous indignation, whereas everyone else just took their lumps. That's baby behaviour.

if an Asian had a monologue like Louis CK and joked about being Asian in Hollywood thing wouldn't be like this.

Exactly. If an Asian got up there and made shitty Asian jokes no one would have cared, but because it was a black and middle-eastern guy, everyone's panties have gotten twisted. But when the black guy makes white people the butt of his joke, who gives a fuck? Certainly not all those Asians who're apparently so concerned with equality... for Asians.

he choose to stand up for what he believes.

He believes racist humor is fine as long as it doesn't offend him, which is why I think he's a twat. Where were the letters when Seth Macfarlane made a crack about Mexicans a few years ago? I'm sure there were more, none of which seem to have bothered him enough to write a letter.

you're not in hollywood so this kind of stuff doesn't affect you

I'm not sure Academy award winner Ang Lee - a man at the top of his profession - really feels the sting of racial prejudice in his career either, he did win two Academy awards after all.
