> Yet if a business used that line to refuse service to a minority, a religious person or atheist, a pro-choice advocate, or a LGBT person (in a nation where these are not protected groups or in a time before those groups were protected), you'd be up in arms about it even though it's the exact same excuse.
Yes, it's the same excuse, but it's not the same facts. There is, in general, a difference between regulating who you will do business with and regulating the content of the speech you will engage in.
