Well, you're right, and in principle I agree. However, didn't some of the businesses get sued for closing ("discrimination)? IIRC some were even "forced" to put up signs in the windows welcoming the bikers! Or maybe I'm confusing this with another event.
No, I think you’re right ... but that shouldn’t happen. Even if a business can’t say, “I’ll rent to a Canadian but not a black this week,” they should be allowed to just shut down, losing all possible revenue.
