A religion which doesn't allow questioning is a religion which isn't confident about its structure.
My mom killed a plastic plant back in the 60's. Left it next to a space heater and it wilted! My grandmother never let her live it down, either. Whenever my mom got even the slightest bit lippy with her, she'd say, 'Hey Linda, remember that time you managed to kill a fake plant? I do.' And my mom would just sit there and pout and stare.
