Why would you, though? I’ve always been baffled by this idea. Art is a method of conveying something, and in that sense, I don’t see any reason not to see that similarly to the artist just describing it, sans what’s intransferable and, possibly, some beauty. If someone speaks of yearning for the world peace, it’s important context whenever they are warmonger of pacifist. Attempting to interpret any art without including the artist in it is, in my opinion, the same as if you conveniently covered parts of the artwork you didn’t like. And that’s just about the interpretation, I can’t imagine myself actually trying to enjoy any Tarantino movies knowing he’s a zionist. Or, for that matter, enjoying reading Rowling. I can attempt interpreting their works via the lens of them being pieces of shit, and that can be interesting, but that’s exact opposite of separating the artist from the art. I can’t see myself enjoying anything made by someone who’s clearly evil, and all of that is excluding the obvious argument of supporting them by paying for or recommending their art to others, just assuming you pirated the thing.
