It's human to lose your shit sometimes. I think he sincerely apologised.
Edit: ok I've done some soul searching and I've realized that I don't really care who they are off set. Be they racists, communists, or nazis IRL, if what they say on the show is funny to me, I'm gonna watch it.
I'm usually like this if it's a one time thing. In his case IDK I just said that because other people still say he is an asshole. But I won't support people that we know are not sorry and would still do it if they could, even if they are famous. Like the unhinged Kanye.
Modern people with the collective knowledge of humanity at their fingertips think any transgression against their standards merits permanent exile into the desert, like in the Bible. Redemption is impossible in the new age of enlightenment.
I see. Very unfortunate. Racism is complicated and more deeply rooted the most will realize and accept. What he said isn't okay and never will be. I hope he's grown since then and made amends for his mistakes.
I think he has moved on from what he did. He was in a semi-recent episode of Comedians in Cars Getting Coffee with Jerry and I seem to remember they spoke briefly about it. Maybe not, though.
Unfortunately for him though, there are no take-backs. Nor should there be. He metaphorically hit the lottery, and wasted all his winnings right there on that stage.
Let's say the cashier at the local supermarket calls a customer some slurs. Someone records it on their phone. it blows up. Should the supermarket fire them?
Banned from jobs that are customer service related forever? No.
This is harder when we shift this to talking about comedians. For a comedian to have a job, people have to want to go to see them specifically. If I go to a show, and have a notably bad experience, I'm probably not going to go see that person / group / whatever again, and if I see videos and read news articles about someone else's bad experience, that's also probably enough to make me not want to see them, too.
So, maybe celebrities that get cancelled should have to find a new industry to work in, if what they did is bad enough. At the very least, they need to change their image to the point that they're appealing to a different audience, if their old audience is no longer interested in seeing their show.
