There's already a legal definition of what is and is not a religion. Nothing that practices human sacrifice qualifies. So what you've presented is not a logical or legitimate challenge to my argument.

Can you just give me a straight yes or no answer to this question....

Do you really believe that a sincere Christian with a genuine moral opposition to gay marriage should be forced to engage with a gay couple, learn enough about their gay relationship to produce a custom product, and then use his personal artistic talents (i.e. speech) to help them celebrate what the Christian believes to be a sin?
