You can choose family and still choose wrong, you can have family assigned at birth and it could be the best. You get what you get in life and eventually it ends anyway.
But here is used in a way of "Yes, I know his views hurt other people, and are more despicable than not, but he's family, what am I supposed to do? I can't ignore them", which is what I'm feeling a bit icky about.
I think art is a lot like family - you don’t get to pick which works really resonated with you and influenced you, even if the artist turns out to be a “bad person.”
