Commitment to your values. Show them the fight, that’s why. If I couldn’t outright deny them service without getting sued, I’d exploit every opportunity to make it a miserable experience for them. You can get the point across and smile without doing or saying anything to land yourself in civil court. My stance is they only get one shot at a “wedding” video and I’d make damn sure it’s one they would never be able to forget. I’d also make it a point to let them know I was taking their job against my will. That would ward off most attempts at this BS and they wouldn’t be able to sue me for it either
Obviously if you are on the opposite side of the liberal gays and/or lesbian issue, you have NO FREEDOM to choose who to do business with. Time for another new law that allows business owners to do business with whomever they choose.
