That post is not that fiery.
You didn't just praise Bill Murray for apologizing, you said that other people that remain cancelled exist in that state, because they were unwilling to apologize. I said that's not an accurate depiction, you offered up Louis CK as an example of someone that didn't apologize profusely enough, which is how cancel culture happens.
For some people a simple apology is enough, for others the apology has to sink to groveling and even then it's not enough, because the more you apologize the more guilty you become. There wasn't an apology that CK could've given that would have changed the results.
It's not the praise of Bill Murray that got criticism, it was your criticism of people who didn't apologize/apologize enough that did.
The person is liked, the apology is accepted.
The person is not liked or the narrative of the act is distorted, they apologize, the apology is not good enough.
And the reality of Bill Murray is probably that he's a charming ******* that can have good momentary interactions, but over a longer exposure he acts like a jackass from time to time. He's an actor, he's prone to narcissism like most of them. That doesn't make him a monster, but he's not the universally fan friendly lovable guy that he gets portrayed as sometimes.
He's also extremely entertaining.
