Boycotts
I should make clear that while I think Robbins is incorrect in applying Constitutional principles to any boycotts against him, that does not mean that I am personally engaging in such boycotts for the most part.
If I limited my reading, movies, etc. only to people who politically agreed with me, I would be in really sorry shape. I could make a long list of writers I don't agree with politically, but are superb authors and write enjoyable books. Same for movie stars.
Heck, "The Natural" is one of my favorite movies, and the story and characters in it represent many virtues I admire and think my kids should too. Should I toss this out of my house just because I think Redford's politics stink?
