I know lots of jokes about Jews or homosexuals or mad people that are very funny. I'd never tell those jokes at work, or at a conference, or in the presence of anyone who wasn't a very close friend.

As pointed out by a previous poster, I would appreciate it you took the time to understand that this was not the crux of what I was saying. Work appropriateness aside, the idea that only juveniles could possibly enjoy such a joke is ... laughable.

That's the whole point. Not that jokes like that are told. I find it sad that some of the ones being told are utterly degrading, and I'd hope people would let go of those, but as far as sex jokes in a group of friends go? Sure. Have at it. They have consented.

At work, I have not consented to be subject to those jokes, and there is no reason to tell them. That is what this is about.
