Why isn't The Bible being taught in schools (i.e., all schools)?

There are private schools that exist that teach the principals of the bible, however they cost money. The reason religious principals are not taught in public schools is because it is considered discriminatory towards other beliefs, but the truth is that it was taken out of the schools because the leaders of this country are atheists and only want the atheist views taught. They don't want to teach humanism and compion in the schools, they want to teach people how to live in a dog eat dog, uncaring, lustful, perverse, competitive world. ;-)
