I think I see what True Conservative is getting at.
Assuming there were no coercive affirmative action laws on the books, and a company wanted to deliberately hire unqualified minorities, or people of any race, then that's their own problem. I certainly don't agree with it. But it's their business to lose, and they can hire whomever they want.
Now in terms of a business denying service to a potential minority customer, I have mixed feelings. On the one hand, a business owner can serve anyone he or she wants. They shouldn't be forced to take customers they don't want to deal with. On the flip side of it, why would anyone want to be served by a business owner that doesn't want them as a customer?
A few years ago, there was this hair salon that advertised "cute short haircuts." It was later discovered that the owner refused to have women over 40 as his customers. There was a whole big stink in the newspapers about it. And I never heard of that salon owner afterwards. I guess enough women found out about him, and boycotted his salon.
More recently, in New Zealand, there was this Muslim owner of a coffee bar who threw to Israeli womem out of his shop when he discovered they were speaking Hebrew. While I hate Hamas supporters with a passion, it was his business, and he could decide who he wanted to serve. As for the Jewish women, I heard they were going to sue, which I disagree with. They should have just boycotted his business, and encouraged others to do the same.
