There’s an important difference: those guys are all dead, and so are their victims. Somebody’s great great great great grandmother won’t retroactively become more abused just because you look at a painting.

It isn’t about enjoying art created by someone who did awful things, it’s about continuing to reward that someone with fame and fortune and giving them free passes to do more awful things just because they have a talent that you appreciate. It’s about valuing aesthetics over morals. By all means, continue to enjoy art made by scumbags. I do. Just don’t continue to bankroll their abuse of others after you find out that they’re scumbags.
