> Yes, the mall’s rules do supersede the rights enumerated in the Constitution. Here’s why. The Bill of Rights protects you against government overreach. It does not protect you when you are on private property.
I don’t think you have that quite right. I can go to the dealership and say whatever I want to say. Their sign isn’t a gag order. If the don’t like me they can ask me to leave. However the dealership is a business open to the public and they’re on shaky ground if they set a conduct standard and apply it arbitrarily. It might even be a proxy for some illegal discrimination prohibited by law ( notice I didn’t frame it as a rights issue).

Yes, but such a thing should not be stretched too far. Otherwise, property rights would disappear. The federal government has laws against discrimination. But anything not covered by those laws should be fair game. For example, many restaurants have a “no shoes, no service” policy. They are discriminating against people who prefer to go barefoot.
That discrimination is perfectly legal. And it should be, if property rights are to mean anything.
