Matthew 10:34Think not that I am come to send peace on earth: I came not to send peace, but a sword.
You're a segregationist if you support the dominican bars ability to refuse service to non-dominicans.
Look, I know this is a libertarian thing.. where one concentrates on the "principle" of a law and ignore its effects. But there are parts of this country that are VERY racist. And if businesses in these places were allowed to choose to serve whites only, then virtually all of the businesses would serve whites only. So if you support the right of businesses to serve whites only, then you must accept that this would be the result in places. There would be portions of the country denied to blacks. Now that might be an acceptable tradeoff for you, but you can't ignore it.
