Whilst I would be the first to admit that there are some unruly pupils and indeed parents and of course there always have been - I am amazed at those who think every school/class is full of those.

I blame Phil "Grange Hill" Redmond. While he may have been re-hashing the experiences of his own youth, in rural backwaters, like where I grew up, it was practically an instruction manual for bad behaviour. My perception is somewhat distorted by the "kicking oneself" factor, as in "why didn't I think of doing that, when I was that age?", hence my lasting view that it was for the benefit of kids who simply lacked the imagination to behave badly.
// Do these include your own offspring or just those of everyone else? //
I decided to spare my potential offspring from suffering by not trying to obtain any, so it's always going to be "everyone else's", as far as I am concerned.
In reality, out of a class size of ~33 (secondary school, late 70s), only about half a dozen were both disruptive and low down the test scoresheets.
They wouldn't allow daily humiliation of class troublemakers, in this day and age. The trouble was, the class thugs knew who the brainy kids were, thanks to this reading out of scores so everyone knew who the brainy kids and they got a lot of stick. It's probably where intellectual snobbery has its roots.
Anyway, based on deeply buried memories like those, I'd probably come down like a ton of bricks on disruptive pupils and be fired or litigated to pieces, before the first week was out.
