Good God man you have worked in schools where children were NOT inculcated with such things, and I KNOW you know what the children (and their parents) were like...

The abuse lies in terror. Luckily I never went to a school run by religions, but I had friends who went to convents, and I know at second hand of the calculating terror wielded by nuns.

Of course, it also lies in teaching madness...
