If the law is harmful, that's one thing. If we are operating outside the law and "trusting" men, then the laws are pointless anyway. (and the way our constitution has been trashed, we may be at that point)
I wasn't justifying this law, btw, merely addressing your statement about reverse discrimination.
It's a twisted web to discuss support for this law (imo) because you shouldn't need religion as a reason to make personal choices with your own business.
But as far as your trust of them "doing harm", I don't see how this law opens up any opportunities for harm that weren't already open in Indiana.
I should also clarify my position regarding your idea that "reverse discrimination" is OK.
Reverse discrimination violates 1 person's liberty. That's tyrannical and unacceptable.
In practical terms, it's also highly subject to corruption.
