(This discussion is for survivors of RC schools. If you survived horrors in public schools, start or add to another discussion.)
I was about 50 and doing some volunteer work when I saw a young woman volunteer whose t-shirt said "I Survived Catholic Schools". (Yeah, you always-horny guys, I liked what was in the t-shirt too; if you need to prove your masculinity, start or add to another discussion.)
Of the one-time RC school horrors. I remember best a fifth grade nun's description of an effect of Hell's fire: with one arm dangling at her side she motions with her other hand as she tells how my burned flesh will fall off my arm.
I remember second best a seventh grade nun's false, in-the-classroom scolding for throwing my books down the stairs. I liked reading too much to treat books that way but she refused to let me reply.
A one-time wonder I remember is a third grade nun's making clear how power-to-do differs from permission-to-do: "You can but you may not."
Of the repeated horrors I remember best being told that doubting (and thinking for myself) is the sin of pride.
A long-delayed insight came after I'd graduated college with a mathematics major. Years of being told to obey without question had damaged my mind in ways I didn't know. Mathematics requires proofs, and proving my conclusions had repaired the damage.
Enough for now. What say other survivors of RC schools?
