Shitty people can make good things. If the things they make aren't connected to what makes them shitty people, and they aren't using their position as a thing maker to spread shittyness, I don't see anything wrong with supporting them. If their things are disconnected from what makes them shitty people but they DO use their position as a creator to spread shittyness, I might still consume their creations but I won't support them. If their stuff IS connected to what makes them shitty people, I probably wouldn't want to consume it in the first place.

For example, if a bigot makes good instrumental electronic music and isn't using their somewhat wellknown face to preach bigotry, I have no problem buying their music and recommending it to others. If they were actively being shitty with the face of their music, I'd pirate it and not spread the word instead. If their music was bigoted, I wouldn't want to listen to it to begin with.
