If I had to reconcile all political, religious, and moral beliefs with a creator before I could enjoy their work I'd have a very dull art life. As Dave Chappelle once said "he gave us Thriller. Thriller". I could also say that good art creates discussion, and that the life of the creator can be part of that. I think this logic however doesn't carry over when we talk of a product, such as a sandwich or say a badly named lipstick, but at some point you do look the other way (I've never seen a mass boycott of smart phones and high end electronics over safe labor violations at Foxconn).
For the record I do not eat at Chick-Fil-A because I do not believe the word "Deluxe" was created to mean "lettuce and a slice of tomato". Not supporting anti-gay bigotry is just the bonus.
