There are authors/artists/singers, etc. whose political stances I disagree with but this does not stop me from looking at their paintings, books, movies, etc.
Plus, most of the movies coming out of Hollywood and elsewhere are the collective work of a couple hundred to a thousand people or more.
http://www.imdb.com/title/tt3460252/fullcredits/ I am not going to skip on seeing the work of so many people just because the Director, Lead Actor, Lead Actress or whoever has a big mouth.
It does depend on the movie's message too though. Some of these I do boycott if they celebrate the trampling of human rights. I do not think I would want to see a Lance Armstrong nor a Bill Cosby movie/TV show.
