As many have said there is no ethical consumption under capitalism, and you can't know everything about everyone, so no matter what you're going to end up supporting something unethical at some point.

That being said, all I can do is act on the information I have, and when I learn about some situation like this, I don't have an easy answer or decision flow chart. But I do ask myself two questions.

How much will my support enable more of the behaviour I find abhorrent? And how much will the knowledge ruin my appreciation of the thing?

I cannot read Ender's Game even though I always meant to since I found out about Orson Scott Card's politics about ten years back. And while there's (somehow) way, way worse people out there the knowledge, especially the holocaust denial, just ruins any enjoyment I could get from the books or movies, regardless of any separate-art-from-artist arguments.

But I am a huge Lovecraft fan, and he was also just the worst. But the guy's dead, it doesn't matter if I buy his books or not. And even then despite his popularity across Geekdom he's a relatively niche author. His views aren't going to reach a lot of people.

I think this works out differently if the creator is someone current and powerful or influential. If we can blunt the impact of a popular creator spreading toxic views that prevents a lot more bad than than the same frome someone dead or niche. Even if that's only lack of support, that's still more.

I guess what I'm saying it is has less to do with the details of the bad views or actions, and more about much my support helps enable those. The less I contribute by watching or buying or clicking, the less I'm concerned about it. Unless it just personally bothers me.

I don't know if that's the right answer but it's the one I've got right now
