It's not a free speech issue, but it is an issue of basic civility. I agree that if someone's speech makes your blood boil then it's reasonable not to buy anything from them. But rational people should always be able to listen to reasonably sensible discourse with which they disagree without having their blood boil. Civil society is poorly served when people can't even bear to listen to any opinion differing from their own.
