I feel like the art is what needs judged here, not the artist. We put all this emphasis on Dahl thought this and Lovecraft said that, and people use that as reason to disregard the entire body of work the person produced. But we lose a lot of work that isn’t really affected by those views and actions because we can’t disconnect it from the person involved in the creation.
What throws a wrench in that is when the person is still alive, and still profiting from those works. Hence why most of your queer/trans friends haven’t bought anything Harry Potter related in a while. Marilyn Manson is my personal example of this. I was a huge fan of his work as a teenager and well into my 20s. When all the stuff about what he did to Evan Rachel Wood came out, I stopped listening to his albums for a long time. I intentionally avoid streaming his tracks because I don’t want to give money to someone I see as abusive toward others, but those albums are still worthy of attention for what they say beyond that subject. Still, it’s hard to hear his voice and not think about what he did.
On the other side of that coin, those managing the estates of these creators that are gone need to be aware of what’s wrong with their charge as much as what’s right. The museum in this piece is doing it right at the end of the day - making the best of a lifetime of antisemitism.
