I grew up in the Silicon Valley, the birthplace of Tech, full of smart, educated people. Not a place where one thinks the religious nuts might hang out.
In the late 70's, my wingnut mother decided a "Christian" school was a better choice than the local public middle school for my Brother and I.
The school she chose was not your standard parochial school - this school was run by a bunch of far right lunatics and had weird morality clauses, behavior codes, archaic dress codes, menial roles for women and the list goes on and on. This was one of those burn the rock music albums kind of place. They were actually on the news for this action. Big bonfire of "satans music" aye yi yi.
Bible class had way more importance than history, science, reading or math. I know because I flunked Bible class

and the repercussions were far more severe than if I had flunked a traditional class. The place was downright scary. I still shudder at some of their doctrine and I am 50+ years old. Thank GOD, after two years of the nonsense my Father put his foot down and demanded we be returned to the local public high school.
