I get your point that double standards and that black people can be overly sensitive about jokes or stereotypes does that mean that white people have to be that way too? I just don't find that particular comic offensive.

Now is it offensive?
you would not say that if you heard what black racism is spewed at lawyer conferences. When discussing race, it is a litany of stereotypes in support of quotas, attacks on non-black peoples, and victimology.
