I don't know why this is so difficult for some folks, but a person (whether they be a niche internet micro celeb or an actual famous person) turning out to be a piece of shit doesn't magically make everyone who ever opposed them ontologically good.
If you were racist, transphobic, or otherwise awful to someone, that doesn't go away just because we know now that they're garbage. There can be lots of garbage.
I'm starting to think they were right when they said Saturday morning cartoons rot people's brains, so many people seem to be stuck in this "one side am goodie-goodie, one side am baddie-baddie" mentality.
