This is 100% a rightwing talking point, pushed by the likes of Glenn Beck, Rush Limbaugh, and Ann Coulter, and I wish it would go away. Look... if we all want to get along, then we need some way of working together despite disagreements. If 51% of people want to do something, we all must agree that that's okay. Otherwise nothing would ever get done.
You missed one piece - a limited government. The 51% can get what they want, as long as it's within the things that we let government do. If it's outside that, then they need a lot more than 51% - like maybe 3/4 of the states.
I’m astonished the National Socialist experiment in Germany is being ignored by this commenter. Indeed your premise is antithetical to Western tradition, which is presumably good because of its endowments to humanity. See: the death of Socrates and the death of Jesus.
