1. Politically, two things turn me off. One is if I know they oppose me politically and spend a lot of their personal money on causes that I think are very bad for America. Second, and by far more likely to get me to notice, is if they seem to have real hatred for people "like me". I don't care a lot if they have different opinions, but that hate is what gets me. Actors are mostly dumbasses, but so are people in general. So disagreements alone don't bother me.
2. For personal foibles... I have a much harder time separating films (visual) from the actor compared to separating music (aural) from the singer.
3. I go out of my way to avoid hearing the thoughts and opinions of the airheads on screen and airwaves, but I also go out of my way to avoid hearing the political thoughts of my friends and colleagues and family. People are stupid, or I'm stupid, but I have very definite beliefs and thought processes. It is very rare for me to hear a political opinion without cringing.
