I am old enough to have been paddled in grade school. I recall a student sticking his tongue out at the principal of that same school and he got slapped in the face (deservedly so). Were those things bad? No, when properly administered they are VERY good.
Somehow that is now considered abuse but lopping off your no-no parts is considered compassion.
The big change was the breakdown of the family.
It started before that. I am certain , like you, that this one thing harmed the school environment greatly though. But you must ask yourself what caused the family to breakdown? I would argue that started with the movement that Margaret Sanger and the feminists put into motion where they ended up detaching sex from reproduction. That was the first stab at the value of life. Then behind that here comes LBJ and incentivizing negative things through “compassion” by hooking the black communities into government dependence.
Folks need to understand that the destination we have arrived at we were not transported to. We walked a long path to get here. And if you don’t like the destination you need to turn around and look from where you came and understand many turns decided on the path got us here.
My prime example of this is Blair White. Blair is a good person in my summation. He has no fantasy in his head about actually being a woman and is against all the current insanity in that arena. Blair openly calls transgenderism a mental problem and has questioned openly if his gender issues were based on trauma from an abusive father. However, I would imagine Blair cheered on many turns on the path that lead us to his point of insanity. The point being, just because you might be against what is happening now does not mean you are free of responsibility helping cause it.
And yes I called Blair “he”. I respect Blair much, but I am not ceding reality to anyone due to feelings or some platitude of respect.
