"I like him as an actor but he seems to have let his newspaper subscription lapse."
I think the less you know of an actor's political pursuasions the better. I actually liked Ed Asner until I heard his politics now I'll leave the room if he's on. I like the old Newman flicks...
There are many movies I used to enjoy that I now will not watch because an actor in the movie has expressed hatred for this country. It's not so much a conscious choice that I will not watch this or that actor, I just now no longer see them as the character they are portraying but as themselves.
