It's still privately owned by the individual. Just because it's assumed everyone can enter that doesn't mean the owner can't tell people to leave.

No, he can't. If you want to be able to make money off the public you have to follow rules.

That's the opposite of what I said. I don't personally condone it but it's the person's right my opinion is irrelevant.

It is not the opposite of what you said. It is not exactly what you said, but it is not opposite.

I know this is a joke but, I don't have to prove it as it is a statement of opinion.

True, but just because you say it doesn't mean anyone has to believe you.

you brought up slavery you don't see me getting on your case.

I brought up slavery after you said desegregation was a bad idea. That was in the ballpark of 50 years ago. You literally want to go back to a time 50 years ago.

I was referring to the comment about me making a mistake by assuming you were smart enough to follow along without needing everything spelled out.

Yes, but it wasn't a joke, it was just a straight insult. It wasn't said to be funny. You were being sassy.

But yes the racism was also unintentional (technically meaning it's not actually racism) learn the difference between presenting examples and condoning segregation.

I am not accusing you of being a racist, for real anyway (The comments calling you a racist are tongue in cheek). You literally said that desegregation is unconstitutional. During the civil rights movement black people weren't allowed into some businesses solely because the business owner didn't want to serve black people. You said laws that force those businesses to have to serve black people is unconstitutional.
