I think you're right, at least in an academic sense. I just associate "minority rights" with "liberal" by applying the principle that people should be allowed to do whatever unless there is a (relatively) objectively justifiable reason to do otherwise. So enshrining that principle in a constitution makes for a liberal and minority-rights protecting component, while the democracy makes for the authority-of-the-majority component which counterbalances it.
