It's not easy to draw line. What about some light racist jokes? Or jokes demeaning wives(fairly common in India) or blonde women? Most seems fine with it but what happens when this line move a bit more further? In Hollywood movies, I have seen comedies doing all this and people applauding it. I believe we need a firm policy of no jokes with a hint of racism or sexism.

Or have absolute free speech. You can't be cherry picking stuffs.
