I would disagree a bit. The concern here is that we are leaving doors wide open for businesses to deny service based on their beliefs. We are accepting that people have no right of due process of the law and businesses can just decide to act as judge and jury to punish anyone they desire based on their beliefs. It is likely that businesses will be never exploit the extreme and be benevolent in exercising this power. However its troublesome that it can happen and that they have this power. One of the core foundation of civilized society is to remove this unpredictability, however small it may be, by establishing crystal clear laws.
