It's not a genuine attempt at legislation by christo-fascists, it's a way to push the overton window, and is also a failure that they can then bring back to their tribe to shout about how they're fighting the good fight against the heathens - so give them money / vote for them. Sometimes it's used to trade political capital. They submit lots of bills like this, the party leadership keeps refusing to support it, the christo-fascists threaten to take their voters and donations away, party leadership gives them some concession by pushing some other bill to lean further in their direction.
