Those rights no longer apply under the Living Constitution. You can either:
(1) lie to the gay-activist customer, most likely accepting the job and then cancelling either a few days later or at the last minute due to a personal/family issue/emergency or health reasons (a polite way of saying that perverts make you ill), or
(2) face unjust courts knowing that you will probably lose, just as MLK accepted the punishment of unjust laws.
I respect either option, given the need to weigh the family costs of overtly fighting evil against the morality of using dishonesty to avoid evil and leaving the fight to others.
This is ridiculous. This is involuntary servitude. A business should be able to refuse to provide a good or service based on any grounds. There are plenty of other businesses who will fill the void.
