I’ve seen people talk about actors and artists that had a terrible time.
My own would be Anne Rice. She wrote Interview with the Vampire after her young daughter died of Leukemia. Then her husband suddenly died of a brain hemorrhage. I suspect her Christian, anti-fanfic phase was a result of mental illness and manipulation from the publishers, although I don’t think she ever apologized.
JK Rowling. Went from beloved to pretty much shunned in a lot of circles I’m in. Still think she wrote one of the best series ever, what happened to separating the art from the artist? does that only apply to male sex abusers, and not women who have opinions?
