Separating the artist from the art is fine.
You can like music by someone who doesn’t share your social, political, or religious beliefs with.

I’ll go a step further:

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.

I agree, but I like to start from a position of “this person probably sucks” because then I’m never disappointed.
