Does Chick Fil A turn away gay? Do they vet customers and refuse to sell their very ordinary chicken sandwiches to them? When Papa John owned Papa John's did he turn away gay customers and refuse their business? What an absurdity that would be.
Selling your product to people is what you are in business to do. You do not have to approve of their lifestyles. The crazy nutjobs seem to think you do. So you refuse to sell to those of whom you disapprove. Really? What do you think would happen if you let them buy your products? Would GOD strike you dead on the spot? Stupid ad absurdum rules. Pity.
