Much like Homer Simpson, I'm prejudiced against all races. It's the only way to be sure you can avoid jury duty.
Joking aside (well, that joke, anyways), I can take them as they are; jokes. Mostly because anytime anyone throws a racist joke or comment at me or my ethnicity, I laugh.
Heck, all the black comedians you see doing the 'Black guy does this, white guy does it like this' jokes aren't hated on, because it's comedy. It's meant to make people laugh and can actually help diffuse tension.
Like anything considered offensive, it's the intention behind the joke that makes it malicious. Are you TRYING to piss someone off, or are you trying to make people laugh? That's about all it comes down to.
