I attended schools in Memphis, and in parts of North Carolina in the 60s, and we didn't have chapters ripped out of books to prevent us from learning about the evils that were contained therein. The school libraries gave even more access to books on civil rights, on science, on evolution, etc.
I was fully informed as to how evolution and other science was the predominant method for learning about the universe, and solving problems.
There were certain social expectations, such as saying the Pledge....some people went along, more rarely some people resisted...(in my case it was long hair, and the stationing National Guard troops in the gym in Greensboro, that put me in direct conflict with the schools... my Dad was a militant atheist, and sent me off to school with 'none' listed under Religion...I don't ever recall it becoming an issue.)
There were certainly no forced prayers at lunch time for example, and I can't think of a single instance of a teacher giving sermons from the Bible in class.
I'm wondering if those sorts of things happened as more isolated occurences, and not as Tennessee Board of Education mandated policy.
Reading that Mr. Metcalf attended schools in the 80s, followed by his litany of oppression made me just a little skeptical...not that such things never happened, but that they all happened to him, with such frequency and consistency. It popped into my mind unbidden that perhaps several horror stories from different people had been combined for effect.
Or, maybe I just got lucky, and all the teachers and principals were not so militant and evangelical....which is why I would like more infomation, since mine is anecdotal.
Having said all of that, I don't discount the very real possibility that there are people pouring a lot of money and effort into creating schools like the one Mr. Metcalf describes, but that frightening future isn't the same as my past experience of the matter.
