But Kate, you forget, for instance, about the restaurant owner who may
not want beautiful and buxom redheads for customers, but is obligated to
open his doors to them.  I know you know that "property rights" was one
banner held-up by segregationists.

You are speaking of a public establishment in which services or goods are being sold to the general public. This was the person's decision to buy or lease a building in which to open up a business establishment to the public.  He or she is voluntarily sharing his or her property and for a price. After business hours, no one is legally allowed in the business without the owner's permission.
