I do not agree with his apology. He shouldn't have issued one.
I listen to Bill Burr's podcast a lot (he is a stand up comedian for those who don't know him) and he has expressed his opinion on peoples apologies after someone got offended.
His point is that if you issue an apology, it is basically you admitting you meant what you said in a malicious way, that's why you apologize, you admit you did something wrong and you are sorry for doing it.
In this case it's obvious that he didn't mean anything in a malicious way and it was a joke. Saying that he won't use that kind of language again implies that "yes, I was being malicious, I won't do that anymore", justifying the offended people.
Instead, he should say "I was making a joke. Jokes aren't reflections of peoples beliefs."
Jesus Christ, you can't make a joke anymore without getting in trouble and have to apologize!
And with that I would like to apologize to anyone I offended saying "jesus christ", I should have been more thoughtful of other people's religion and not implying that my religion is true and theirs is not. I was way out of line saying only Jesus's name and not including other messiahs and gods of other religions.
