That would be liberty for you

But then I think.. you couldn't refuse to make a cake for Jews if you were a Christian, right? Could you have a sign above your bakery "Whites Only"?

Yes. and Yes. I would hope such a place would die from customers' ostracism, but whether it did or not, that would be liberty for you.

When I was young, we frequented a burger place (pre fast food days) that had a sign by the door, "We reserve the right to refuse service to anyone." I was much older before I realized that was racial code.

My home town in the 50s was 'benignly segregated.' I remember the first time I saw a black couple in a restaurant after being away for years. Nicely dressed middle classish, but the guy had one of those pick-combs sticking out of his hair. I wanted to joke with him he'd forgotten something, or ask him did he know how dumb that looked, even mildly threatening (black man with pointy thing!). But that might be taken as racist. :/

I thought of that sign, though. No, sir, we are refusing you service, not 'cause you're black, but because you don't know how to dress or act. Which, actually, is the cultural reality underlying much of 'racist' discrimination. E.g., we aren't opposed to TFG based on skin....!

You either permit liberty or you enforce tyranny. My sympathies are anti-bigot - utterly with the blacks at the lunch counter - but just like defending the right of free speech for words I detest, politically I oppose government insisting anyone must serve anyone.
