Blacks pay the taxes that built the streets, sewers, and water supply to that business. If that business wants to exclude those people then they can do without those services.
Actually those businesses pay a great deal more than any individual citizen for the services you list so why is their right to refuse service less valid that the government granted right to be served? If we follow your thought to it’s logical conclusion then no business owner can refuse service to anyone for any reason. Pedophiles pay taxes, should Chuck-E-Cheese be forced to serve them. Men pay taxes, should Curves be forced to accept men into the women’s gym? Homosexuals pay taxes, should churches be forced to host their “marriages?”
You seem to be saying you don’t believe in private property.
My taxes helped build the road that leads to me next-door neighbor’s driveway, but that doesn’t mean I have a right to park my car on it.
