I would like to think the truly right-wing-- in it's best sense-- attitude would be an appreciation for the ability to openly voice these opinions and the ability for people to openly disagree with you. If you're getting downvoted by individuals for your criticism of a private opera house's policies, that's a win for personal liberties, not an indictment of them.

I don't mean to strawman, but it seems like you're advocating for the exact opposite of what you claim. You want an authority to step in and tell these people downvoting you that they can't have their opinions? You want your viewpoints to have a certain number of mandated agreements?
