Most of the people who have written about it not being fair are saying that he has changed and he should be given credit for who he is now, not punished for something he did long ago. I don’t know the man, and didn’t see the other movies he’s made or follow his social media. I do support Disney taking a stand and sticking to it. But I can understand the viewpoint of those who think he’s changed and should be given credit for that - because I believe people can change if they choose to. But that doesn’t automatically mean there are no consequences for your prior actions.
For the record, from the bits and pieces I have read about what he posted, it was vile and he should be held accountable for his words.
