This is hardly surprising. And it starts much, much younger than that. And it has been going on for a long, long time.
I can remember being in 2nd grade, in the early 1970's, and having my staunchly and insistently vocal anti-gun teacher openly berate and call candidate Ronald Reagan the devil- carrying on about 666 and blah, blah, blah... begging us to convince our parents to vote for Carter. She was also a Dallas Cowboys fan.
She was detestable on every level....
In my very first act of political disobedience in life, despite a ban on toy guns (or even GI joes) for show and tell, i made sure i brought my brand new plastic M-16, wrapped carefully in brown paper, to school. You shoulda seen her eyes when i unwrapped that puppy in front of class.
She called my dad in to rant....but dad was a Philly Cop under then mayor Rizzo, a veteran, and had taught me to shoot at age 5. He showed up in uniform, complete with his sidearm in place, and told her to stuff it.
