It's like the eternal dilemma of if it's possible to separate the artist's work from his private persona. I'd say you can't but that in no way diminishes the value of their work. Great artists were supporters of horrible regimes: Knut Hamsun supported Nazis, Coco Chanel was their spy and profited from the perks of being their racehorse. And yet we don't see people throwing away Chanel bags or clothes. Peter Handke supported Slobodan Milošević yet he was awarded the Nobel prize (which caused great dismay among his victims). I went to see Tschaikovsky's Nutcracker the other day, a Christmas tradition of mine, though I despise Putin and his politics. Maybe because I've seen actors who had their whole lives and livelihoods destroyed by their government if they dared to cross the border, artistically at least. That's why I don't condone canceling Russian culture as such. In my experience, those who were compliant in discrimination of Serbian artists in Croatia were prone right-wing conservatives who also seeked to "purify" their mainstream culture from sexual minorities, atheists etc. Fortunately, it's clear you're not like that. Art is meant for building bridges, not walls.
