Really? Tell that to Mel Brooks and Sarah Silverman. [1][2] Comedians routinely joke about the holocaust, and have for decades.

What about child porn? Pedophilia? Human trafficking?

I'm utterly confident that if I looked I could find examples of comedians telling jokes about those subjects and audiences laughing.

For example, I just searched Google for "comedian pedophilia joke" and the first result is about Louis C.K. doing one during an SNL monologue.

Nothing is off limits in comedy. Plenty of stuff is in bad taste, but as long as the comedian is actually trying to be funny I think most or at least many other comedians will back them up.

There’s plenty of jokes about the abuse of children by the church.

You'd be surprised. Tons of major professional comedians have jokes about the holocaust.

You've definitely been added to a list somewhere for all those searches, lol.

There's a long-running Holocaust denial joke in most episodes of Norm Macdonald Live that's hilarious. You're just not watching enough comedy if you don't think anyone makes Holocaust jokes.

Mitchell and Webb sketch about nazi SS death squad is one of the best one, and often quoted by other comedians.
