Conflating everything about a person into a single "I like them" or "I don't like them" variable makes it harder to accept that a talented, attractive person who knows all the right gender words, can still be a bad person. It makes you more likely to, if someone made art you dislike, to look for reasons to believe that they're a bad person too. It makes it difficult to accept that a bad person can still do good things, or that a broadly good person (like you, perhaps) can do bad things.
