Indiana RFRA: What's The BFD?

The "why now" issue / look at what the backers say would be a powerful argument even if the Indiana RFRA law is just plain benign. But, this is far from clear and rests on litigation (meanwhile, some under the radar discrimination will go on, probably furthered by the law). Plus, especially post-Hobby Lobby, the federal RFRA is not free from controversy itself.
