There are no end of reports like this --- a kid in a nearby elementary school system was suspended for doodling a cartoonish drawing of a handgun in a notebook. But to call the school administrators "idiots" and label them "irrational" is to miss the point. None of these people advance the argument that they are somehow protecting students by their "zero tolerance" policies. Nobody could keep a straight face while suggesting that a tiny toy posed any actual threat (other than maybe a choking hazard).
Rather, what these insidious policies are all about is advancing the hoplophobe agenda of the school admins and their allies. They aren't really worried about toys, they just don't want kids becoming acclimated to, familiar with, comfortable around, guns. They want to demonize guns. They want gun use and possession to be stigmatized, and marginalized. They want nothing but negative associations with guns. (Guns are bad because the only uses we acknowledge are criminal acts.) These people aren't irrational, they're using time-tested brainwashing techniques against children, their parents, and the general public. Keep repeating the Big Lie that guns are bad, gun people are bad, &tc., and eventually enough people will come to accept the lie that it becomes part of the social and political lexicon..
These people, should, figuratively speaking, be taken out and shot, by removal from their jobs and positions of authority.
See if you can get any traction for this concept at your next PTA meeting...
