I agree with these. I look at it as personal decisions I hope I wouldn't make but can't ever know someone's situation to know where they come from versus absolutely morally reprehensible things which sicken me. I suspect there are plenty of artists who have done things which would make me refuse to listen to their work/read their books/etc., but about whom I don't know anything. I tend to not get too interested in the lives of public figures I don't know.
This was the first one which jumped to mine. I absolutely will not listen to/watch anything I know he'll be on. My opinion of Rihanna has changed and I can't enjoy anything by her now. I do understand that it's emotionally difficult to get away from an abuser and so don't blame her, but on an emotional level I am still now repulsed by her music because of the example she's setting for the girls of our world.
Tom Cruise is the other one who comes to mind. He's just such a weirdo. There are so many bizarro stories out there I have no idea which if any are true, but I just think he's... off. And I haven't seen anything of his since the couch jumping episode out of not wanting to see anything he's made, but not because he made it. I suspect that suspension of disbelief will be harder next time I see one of his movies because he's become such a personality beyond his characters. This kind of amuses me given I don't have that problem when I watch my college roommate, but she's a FAR better actor than Tom Cruise ever was.
