Sorry, I didn't mean to be obscure.
Another poster asked if it would be OK if an owner fired a person because of their ethnicity.
You responded that it would be OK because it was their business.
I responded "not for long."
By that I meant that the owner would be sued and perhaps would lose the business. It was a joke answer but the message was serious.
You may think that in an ideal world an employer can fire on whatever basis he wants, including race. In the real world, that is illegal discrimination and the owner will be sued and will lose. The only question is the amount of the damages.
I understand the real world. That does not make it right. We are supposed to be free to associate as we desire. Free to run our own affairs. How is this free? I know, I know, it's not allowed. That does not make it right.
