No need to feel cheated. Education is a gift you give yourself, and it has little to do with schools. Most of what we learn is seriously flawed. Learning to sort the wheat from the chaff is a tough gig. Most curriculum plans are laid out with other guidelines than truth and fact. Bias blinds and warps the best intentions, so little of what is gleaned in school is untarnished. I had professors tell me "You're right and we both know it, but I can't say that in class". A friend was a quarter or two from a divinity degree when he was told he couldn't tell church history as it happened because "the congregation isn't ready to know that, just tell them what they've always heard". Being told the truth wasn't welcome sent him to art school. Jesus said the truth will set you free, Jack said you can't handle the truth. one has to find the courage to walk that path one's own self, but marriage, job, kids, get in the way, and where one's bread is buttered emotionally will hide the truth.

It's a grand journey. Enjoy the ride.
