Not attempting to get too deep into this conversation, but with Churches you at least have an option of going. Don't like what their teaching? Don't go. School is one of those pesky things that the government feels necessary to make mandatory. I know that there is home schooling, but it's really not a viable option for many families. I'm not saying that creationism should be taught, just that there's a flaw in your statement.
Sarcasm does not type well. Yes, I'm kidding. 6 years after the government tells me I don't have to go anymore, I'm paying money to get more. I'm in the middle of my master's degree right now. Believe me I'm kidding. I thought more people would pick up on the sarcasm.
The fatal flaw in the whole train of thought is the assumption that those with education are actually intelligent. Sadly enough, I know many very ignorant, but well educated people. The reverse is also true.
No offense taken, I need to learn that sarcasm doesn't type well. Although, brainwashing children in school doesn't sound unlike something the government would do......., I really am kidding.
