This is like Bart's "gay cake" thing again. You should be able to refuse service to anyone you want.

Yep. If it's your property, your business, or etc. of yours then it should be up to you who you choose to deal with.
We had a minor debacle down here earlier this year because the "escort" girls on Back Pages (like Craigslist) often posted "No African-Americans".
I suppose some judge should order them to **** black guys since the business these girls are in is arguably just as public as a bakery.
(The courts punted on this issue because the escort services were unlicensed and therefore the plaintiff had no 'standing')
