When I was a freshman in HS we had a Civics class that was mandatory. .......In addition to textbooks, each student should be required to have one of the pocket sized books of the Constitution... and be tested on the contents!
That might help the kids to better recognize in later grades and college (if they go) when the texts and teachers are not telling the truth.
The problem is what will this liberal school version of the Constitution say and what will leftist biased the test ask?
