I disagree that it has been happening for generations. I am now 60 years old but I can assure you that even the worst behaved kids that I went to school with, present company included, would ever think of treating an adult the way these kids did. There was always a certain amount of respect and consideration that adults, all adults, were given. Kids would pick on and bully other kids, sure, but even then there were limits. As cruel as kids were to each other, there were assumed consequences for crossing the line with an adult. Mouthing off is one thing, doing what these kids is way, way beyond that.
The BS that Barney and Friends injected into kids heads was reinforced by their parents and those same parents forced the schools to do their job of raising their kids while not allowing them to so much as hurt their feelings much less paddle their ass when they so obviously deserved it. And now we get to see the results. :sigh:
Can we agree that maybe this happened on one school bus per generation? After all what we have here is one school bus on one school day. I'm not convinced that it is representative of an epidemic.
Where I do harbor concern is in areas that others have mentioned, namely that in the USA power over another may be oversold as a virtue or false representation of inner strength.
I was no saint either.
