How many cases have been brought?No court has allowed a RFRA defense for discriminating.I think we should dismiss out of hand unequivocal statements of this kind. Lawyers never talk like this. Politicians sometimes do, but then they just want to get elected--and no politician can keep promises after he's dead, so that kind of puts a crimp in a "never" statement.And no court ever will, and if they do, it will be overturned on appeal with a rebuke.
Anyone commenting on the law can handicap what will happen--that's what lawyers get paid for. No one can predict what will happen, forever, in the future. And interpretations of law change. That's like someone saying "No one will ever make you send your child to school with a ******" after SCOTUS decided Plessy.
When you're less certain of yourself, you'll be a better debater.
