I don't know why it ever "seemed" that way to you. It was never "tin-foil hat stuff." Those of us who've been following the unfolding tragedy and horror of the government school system for years have been well aware of what's going on in there for a long time.
I guess the good news is that you are one more person who finally has awakened to the deep cultural sickness of the government schools.
Because I'm talking about 10 or 15 years ago, when the indoctrination wasn't nearly so pervasive, adamant, and conspicuous. That has only developed in the last 10 years.
