Misses the point. They have the right to be lunatics without being forced by government fiat to provide services to either customers or employees their beliefs prohibit, just as no one is forced to shop there, or work there. Mock and criticize their beliefs all you want, that’s legal. Force them to break it by government force, and you’re as bad as anyone else who forces another to break their personal conviction.
One might as well say that a Jewish butcher should provide pork to gentile customers and employees because they demand it and the majority of people don’t believe in keeping kosher.
