This is my first topic/post, and forgive me if this has been discussed before...
Personally, I think that both parents and schools should only teach kids the very basic things they'd need to lead a successful and rewarding lifestyle, and the abilities that allow these kids to make up their own decisions once they reach the age of consent, when they are mature and educated enough to decide on their own, without someone else imposing their beliefs onto them. In short, a neutral upbringing.
That's what my parents did with me; both of them have different beliefs, and never once did they impose any sort of faith or belief system onto me. Today I am a happy atheist, and it was solely my choice; no one taught me about what religion is better, or that god does or doesn't exist. I just "grew up", learning math, morals, physical education, literature, world history, etc....
I think that work for our world. Of course, that's just me speaking, personal experience and all. There'd almost have to be some sort of observer that would analyze my life and determine if there really wasn't any influences,.... But the concept in general, should work.
Logic and morals for the practical applications of life, and religious studies as a basis for understanding the world that surrounds us. The religious aspect though must be carefully taught. Time studying Christianity should be equivalent to time spent studying Judaism or Buddhism, or whatever. It should be taught from an anthropologist’s point of view.
Perhaps "very basic things" is not the best term to use... What I meant was teach people the main things we should and are learning, it seems to be working. But when it comes to teaching religion, nothing specific should be taught. The students should mature to the point that they can make their own decision towards what faith/belief system to follow. This applies to both school and parental teaching.
I would prefer to remain discreet as to what beliefs my parents follow, but rest assured they were not raised as I was, and they are loyal followers of their beliefs.
As for the history I learned, nothing too elaborate but I learned a good deal about the different great empires of ancient civilizations, leading to modern history. I looked at a lot of different books, whatched historical movies and dockumentaries, etc. I did not read the bible or any other holy scripts, so don't judge me too too quickly.
