If you're still saying stuff like this you're either a troll or just fucking retarded.
It's not about "making racism legal" it's about allowing a private business to decide who they do business with, based on whatever criteria they want. Maybe they don't want to serve you because you drive a Honda, or because you have a mustache, or because you're white, or because you aren't white, or because you dress suspiciously, or because you have brown hair, whatever. They provide goods or services and you are privileged to be able to purchase those goods or use those services. They don't want to do business with you, should be "Too bad, you don't get a say in how my business functions."
But I forgot, not letting someone use your optional service is comparable to forcing harm upon them, such as shooting them in the face.
You're a member of the "Healthcare is a right!" crowd, aren't you?
