I tend to agree, except that it's a bit more specific than that, as in 'no gay weddings served'. If he were asking all his customers their sexual orientation and refusing to serve anyone who answered LGBTQXYZ and/or K (I'm just making these up), it'd be more of an issue. The only reason it became an issue is because they asked for a gay cake, which presumably is not a common thing.

So yeah, I do agree with you on one level. I also think though that until secularism overrides religious rights, then his right to be a bigot based on his religion has some theoretical value. Although if the KKK was a religion I don't think the same argument would work. Eh, what do i know.
