Schools are an instrument of the state. They exist to teach the “right” kind of thoughts so the students will conform to the government-approved ideology.
In so many instances, some of these school districts seem to be going out of their way to find these assortments of weirdos to speak to their children. Wouldn’t it be just as easy(or easier) to find normal folks to speak to the kids? That was the way it worked when I was in school. Maybe the weirdos didn’t exist back then...???
