Why blame teachers? I blame the parents.
The federal government.
The federal government unconstitutionally strong-armed the states into banning prayer and the Bible from schools followed closely by putting away teaching the Constitution.
Government by its very nature HATES the Constitution because the Constitution LIMITS the federal government and the feds HATE being limited.
Are Patriots as clear and determined to restore our Free Constitutional Republic as the Left is determined to destroy it?
So far, it looks like the Left is winning.
