The Illinois thing is going to last exactly as long as it takes for a gay, black lawyer from the NAACP to fly down there and sue their pants off because they refused him service because he was black. The US has laws against discriminating against people, and this was rather thoroughly hashed out in the '60's and '70's. Unfortunately it looks like we're going to have to hash it all out again because someone found a loophole.
Basically, if your religion says you have to bang your forehead on the ground nineteen times a day, that's fine. If your religion says you have to bang someone else's head on the ground, you are going to run into problems.
Of course, then there's the corrupt police forces that beat people up and kill them because they're some sort of minority, or just because the cop feels like it. But that's sort of a separate issue.
