As a child, I went to Sunday School but never paid attention. As a young adult, I saw a World Religions class in college but opted to do my own reading instead. I never actually read the Bible (and by that, I mean the Hebrew Bible) until I began the process of converting to Judaism, at age 35.
My "ignorance" was of my own doing - I was offered the opportunity to learn about the Christian Bible when I was younger, but I declined. I was interested in finding my own way, as are younger people of today. If my parents had forced me to continue with religious classes, I would have ended up resentful of them, and of the religion. Instead, I finally came to realize that while I wanted to have a spiritual life, it was not in the religion in which I was raised.
Your friend from Sweden learned Christianity in school because it is the official religion in Sweden. Because the United States has no official religion, there is no role for that sort of education in school, and it is, rightfully so, taken care of in our religious institutions, which are kept separate from schools for a good reason. If you are to suggest teaching "the Bible" to children, I would ask which Bible? The Hebrew Bible? A Christian Bible? Which Christian Bible - there are many versions out there. What about Islam, Buddhism, Hinduism, Sikhism, and the multiple other religions that we find in the United States? What about Atheism?
Your proposition is a dangerous one. Our country was founded by people who wanted to practice their religion freely (or in some cases, not practice religion). Teaching the Bible, whatever form, has no place in a public educational system. We already have enough people who are trying to force their religion down others' throats - please do not suggest that we go against the freedoms outlined in our Constitution and implement such a thing.
