As if religious belief violates civil liberty?
Government schools never were, are not now, and never can be religiously neutral.
Solution: Begin the process of privatizing K-12 education. Work toward complete separation of school and state.
At their inception, our nation's system of K-12 socialist-entitlement and single-payer schooling was generically lukewarm in its Protestant worldview. It became progressively secular and by the 1960s was utterly godless. None of it from the beginning was, or is, religiously neutral in content or consequences.
Today, any child who cooperates in the government's godless classroom **will** learn to think and reason godlessly. They must just to participate. How could it be otherwise? How can this be religiously neutral? ( Answer: It isn't!) And...They risk learning that privately held religious belief is to be thrown in the trash can at the door to their public life.
