Granted, it wouldn't happen now most likely (I hope) but there is a reason that laws were drawn up to prevent gross racism.
This is the paradox of the system.
If you are living in a society where racism is tolerated, then a whites-only bar that routinely beats up and throws out black people would stay in business for a long time, and it would perpetuate the racism throughout the society. Government would come in and make that racism illegal, which would help to make society intolerant of racism. But then once you have a society that is intolerant of racism, do you need the anti-racism laws? Can't you let the whites-only bar exist, knowing that it's not beating up black people?
But that begets the question, why was there a racist bar that beat up black people in the first place? Shouldn't it be illegal to hurt people? Well yes, unless the government supports your racism.
The truth is, the free market is inherently non-discriminatory, and it promotes catering to a wide audience as opposed to just the majority. It's only when government supports racism by limiting the natural rights of a group that a racist market and a racist society is perpetuated.
