I’m afraid some school administrators don’t want to preserve our government as it was set up in the constitution.
The teachers and their union certainly do not. Here is a book (hard to find now) that the N.E.A. purchased from 4-H in 1941, published through the 60's, then killed (had references to God and Jesus, the bible, liberty, the constitution, etc.). Thousands of remaining copies were then buried in a landfill.
