Comedy can be silly and gross and offensive, as long as there's sort of a point. You can make a joke that, on the face of it, is racist. Ostensibly someone can appear to be racist, but if you know you're making a point about race, and not just being pig-headed, then you can do that. I think some people who don't understand comedy will have a knee-jerk reaction to some stuff, and will always be offended by it because they don't understand it. Some people react to it in a vociferous way, which is unsophisticated, but there's always going to be those people out there.
