You clearly have not experienced discrimination before. It's not just the act of being discriminated against, it's the memories that it invokes and the reminder of how little has changed.
Believe me, friend, I have experienced discrimination. My entire family has. They have been driven away from their home because of their nationality. Then I was mocked and humiliated by other kids as the-kid-who-cant-speak-our-language. Then there was the high school and all the "nice" things it holds for the nerds. It might well be that I have experienced more discrimination than some of the furiously anti-sexist people here. Yet I don't have anything against racial, sexist, religious or other kinds of "sensitive" jokes. They are jokes. They are not meant to be taken seriously. It's OK to laugh at them if you find them funny. If you don't, shut up and let other people laugh. Don't be a self-important asshole. After all, your precious nationality/religion/sex/sexual orientation is worth exactly nothing.
