In this day and age, why would you be stupid enough to use your religious beliefs as an excuse to deny someone services?
There are plenty of ways to avoid entering into a business transaction without having to appear discriminatory at all. When I worked for a private repair shop and encountered a client who seemed to be more trouble than they were worth for whatever reason, we used to simply say, “I am sorry, but we cannot provide service.” If people questioned why (which they did, very often and with plenty of attitude), we just kept repeating the same phrase: “I’m sorry, we cannot provide the service.” No one interpreted us as being discriminatory, or went as far as attempting legal action. We were simply annoying, so they moved onto a business that was willing to enter into the transaction. No harm, no foul.
That is the beauty of the free market: You have choices. If a bakery simply said “I am sorry, we can’t provide that service,” and left it at that, a gay couple denied service might interpret the owner’s choice as being discriminatory, but they wouldn’t have a leg to stand on in court. You can’t sue based on an inference. Progressives, however, rely on the courts to push their agenda because Big Government is their god. So the minute you breathe a hint of something that could be misconstrued as an opportunity for a lawsuit, they gain home-court advantage.
By simply saying, “I am sorry, we can’t provide that service,” you may be opening yourself up to some annoying picketing and internet memes, but what’s the worst that will do? Throw you in the same court as Chick fil-A? We all know how well that protest worked out. The bottom line is, you’re letting the free market decide your fate, not the courts.
