This was by design.
My mom taught civics for 30 something years until they ended it in 1995... and this was in largest/second large public high school in America.
They also did away with Western Civ as well at the same time.
Deliberate ignorance.... but HEY it is okay, they learned all about warm things like women’s history or hyphenated-American history and Social Justice LOL.
All the while just omitting real world history and the classics all together.
Jerry Brown now has primary school students being taught about homosexual contributions to history.
We learned Western Civ in high school. It taught, among other things, of the threat of Islam. Too bad it's no longer being taught in schools.
The reason some societies held on to their God given rights like jealous lovers was because they were reminded of them often in schools, newspapers and public proclamations. In Great Britain, Magna Charta was read twice a year in public places, not that it would lose its validity without such confirmations, but to fix the contents of it in the minds of the people.
If neglected, we were sure to descend to the pitiful condition of man in mainland Europe, where they accepted their very existence at the whim of a despot.
A republic cannot be maintained by a people ignorant of the traditions and ideas essential to their political happiness. We are very close to accepting the pitiful, slavish condition endured by most men through history.
