You're right, they aren't.

ah yes, the infamous multi-cultural white supremacist group who marry black women

Well you're wrong. Allow me to lay this out as thoroughly as I can: Teenagers love being edgy, i.e. they love outrage for the sake of outrage. Hitler is outrageous (and well-known), thus he features prominently in "rebellious" humor. There's nothing wrong with this, because the premise of the joke rests precisely ON the fact that associated atrocities are inappropriate, or perhaps the logic is absurd. The jokes only work because Hitler, or more generally racism, or whatever, is wrong, furthermore that the general consensus is indeed that is is wrong. In fact, the more you kvetch, the funnier it is (to a teenager).

Now, perhaps modern "jokes" have you confused into thinking that comedy is just a smug-and-response between some wank and the audience, but this is not so. Personally I want grit, I want ambiguity, I want the full range of human experience out of life. Humor is many things, but it is at least a way of getting a handle on the unsavory inevitabilities of life. If you want to succumb to a fear-based ideology and spend your life constructing an unlivable, bureaucratic tangle of anti-boogeyman legislation, go ahead, but do the humans a favor and leave us out of it.

>There are actual consequences to people.

No, there aren't. No child is being unknowingly radicalized by inappropriate jokes (except maybe as a response to the twits taking up arms against them).
