Okay, just playing devil's advocate here, but remember when the bakery didn't want to bake a cake for a gay wedding, and everyone was like, "It's their business! They should be able to refuse to bake the cake!" And "Any private business should be able to refuse service to anyone for any reason!" There were a LOT of people here on INGO expressing those feelings. Now that we're (gun owners) the "gay couple" (figurativey speaking), not so much. Just sayin'...
I do not see the comparison here. My POV on the bakery was if they do not want your business, go some where else. Pretty much the same here.
In this case these places are access to an entire class of people. Whereas the bakery said come on in and get a box of Napoleons or turnovers.
