I have no problem with "offensive" humour. I'm just not too keen on him though. All humour is offensive to somebody, that's why we laugh. It doesn't mean we think that way at all, it's just a release.
I'm totally non-racist in any way, hate racism with a vengeance, but racist humour is not offensive to me, nor is anti-gay humour. If it's done with malice then that's a difference, but if it's tongue-in-cheek (as most is) then there is nothing wrong with any humour.
If you can laugh at yourself then nothing ever shakes you! I'm a complete fool in some ways, I know it, and laugh about it.
