Not to suggest that if he threw out blacks, I'd oppose prosecution, but that's not the case. This is a civil dispute, apparently nothing about throwing Jews out of the hotel violates civil rights legislation.
BTW, if this were a private business, they could bar Jews and anyone else. When you open your doors to the general public, you've lost that defence of privacy.
You are correct that breach of contract is a different matter. I was speaking of government enforced laws on discrimination.
The part about a private business losing rights by opening its doors to the public, however, is incorrect. It is still a private business, and it ought to be able to accept or reject any customer for any reason, even if that reason is distasteful to the rest of us. I guess the only reason business can use now is if the person isn’t wearing shoes or a shirt. They do not have to let anyone and everyone in their place of business, though, and can ask people to leave the premises. That is not against the law unless the person claims it was a case of racial discrimination. Next, will be sexual orientation, and we will see where that leads.
I understand why people are upset that anyone would treat people this way, but do you not see that the government is using this to limit freedom? If you want to rent a room in your house, you may not have a choice to refuse anyone if the government says that you are discriminating against him in some way. That is government running roughshod over your rights.
Again, check out what Walter Williams and Thomas Sowell have to say on the subject.
