When it comes to comedy, what crosses the line?

As we all are very aware of at this point (literally everyone and their grandma knows about this) about the whole Dave Chappelle controversy. (I'm surprised no one made a debate about it until now lol).

We all know, how, in Dave Chappelle's "The Closer", he says he's "Team TERF" (trans-exclusionary radical feminist), and we all know the backlash of said joke. In my humble opinion, say what you want, I do not care, but you'll have to deal with the consequences of what you say. Take this as an example, say you're a big patriot, you would die 7 1/2 times for your country, and somebody jokes about 9/11. You would be mad, wouldn't you? You don't joke about controversial things, because there's sure to be a backlash against you, like what's going on with Chappelle. I reiterate before someone says I support the anti-Chappelle movement, I do not care for what a comedian says, but you have to deal with the consequences and subsequent backlash from others.
