Ri-i-i-ight. It could not possibly have been that having faced extremely hateful behaviors from the Right for the simple act of failing to get a timely haircut or mentioning that blacks should be permitted to vote or buy nice houses, that the boomers simply responded in kind.
Common sense: the sum total of one’s prejudices.
Mods and Rockers, (or frats and grease), for example, could never be legitimately accused of having a careless appearance. Hippies, against whom the charge of “careless” dress might have been laid, were always a fringe element and were pretty much apolitical. Yet all those kids were subject to arbitrary punishment or harrassment at one time or another. So it seems to come back to being punished for nothing more than being different. That was a good example of “manners” that you wanted them to emulate. In my memory, a very large number of the people who threw out “manners” were people who had been subjected to arbitrary slights and punishments for the horrendous crime of not looking the same as some other people.
I came into this thread thinking that you simply suffered a sense of loss regarding some aspects of your memories of childhood, and had created a set of villains against whom you could rail at that loss, supported by more than a bit of confirmation bias and faulty memories from forty years ago. However, you are now just flinging stuff against the wall and hoping it will stick. You are making up a history that you would never be able to demonstrate with actual references to actual events in a coherent timeline (which might be why you have avoided actually providing any historical support for your odd claims).
Since you appear to be more interested in simply having a shouting contest with others on the board, I will stop trying to interject any historical or factual references into this “discussion.”
Have fun (as I am sure you are having) and I will now get off your lawn.
