If you're claiming the Christian has the power in this case, I'd say you've been buying too much Rocky Mountain High. 

The gay couple asked for a wedding cake, Phillips said no, the gay couple made a couple of impolite remarks, flipped him half the peace sign, then went to another bakery and got a cake for free.

The baker has been fined, his staff "re-educated," forced to document his compliance with the law--and, as a result, he shut down his cake-making business. 

The score is Gays 1 and Baker 0. 

But this really isn't about Christians vs Gays. It's about conflicting rights of individuals. Gays can get married if the baker wins or loses the case. But if the baker loses, he'll likely go out of business.

By the way, it's legal for gays to be Christians--thanks to the First Amendment.
