Separating the artist from the art is fine for me as long as you don't support them. There is nothing inherently wrong with consuming media you like from a controversial figure.
Of course it's hard to separate the artist and the art if you actively give them money for it.
I like some of Kanye West's music but I would never spend a single cent on one of his albums, watch an ad on Youtube for his music videos or listen to his songs on streaming services.
It depends: if you only listen to music (or view artwork) to feel "good" or enjoy "basking" in the emotions it evokes, then it makes sense to steer clear of artwork you disagree with or makes you uncomfortable.
But if you find value in viewing artwork that illicits a multitude of emotions, evokes introspection, throws you off balance, and forces you to consider concepts you wouldn't otherwise, then taking a moment to peak into the mind of someone you fundamentally disagree with is a great way to do that.
As Werner Herzog put it, "the poet must not avert his eyes".
You have to separate the art from the artist because there is not a single artist I've ever encountered who wasn't some kind of fucking trashhole of a person.
Artists spent their lives on being artists, not developing good interpersonal skills or understanding politics or philosophy.
Beleiving an artist is a "good person" is just setting yourself up for disappointment. Start out assuming they suck dogshit and you usually end up being right.
I think it's reasonable to draw some lines that, when crossed, you'll choose to disengage from their art.
The musician doesn't have to be a saint. But if I find out they, I don't know, love eating live puppies, I'm going to prefer spending my time and attention elsewhere.
This is actually really popular among my music students. I completely disagree on most case. X raped 300 kids but hey, he makes pretty good beats so let's pay 200$ for a concert.
