I'm an Agnostic, raised Southern Baptist, with Methodist leanings. I don't buy a literal interpretation, and notice that some of the behavior of prophets in the Old Testament sound as much like schizophrenia as they do revelation. However, while I'm unconvinced of the Divinity of The Christos, I do support the core message: pacifism, kindness, charity, and - above all - that the purpose of life is not measured by what we can eke out of the world, but how much better we make the world for others, especially those who need help the most.
So, I don't agree with your contention that religion should not be taught to children, but I do agree that Christian sects are teaching their children the wrong lessons.
