It signals a broad lack of education and a propagandization.
yeah, it's not just a lack of education. I've suffered from a lack of education, solely because I hated history in high school, and didn't pay a lot of attention. I have recovered, and have since learned many things. I'm no scholar, mind you, but I have a pretty good base these days.
The propagandization - that is strong. I learned something I never thought I would when I went back to college some 15 years after finishing high school. I learned that things had changed a LOT concerning how history and social order was taught. The mid 90s was my great awakening to the lies and distortions that were being taught at the college level, at least at some schools.
