“This isn’t “apples-to-apples.”
Right, it’s a complete non sequitur.
I doubt rates of suspension have anything to do with integration, and most urban schools are majority black nowadays, if I am not mistaken.
Bad behavior (or perhaps it’s overzealous punishment) in school has to do with other societal forces, I doubt 13% of all children were getting suspended back in the 50s, although that is clearly just a guess on my part.
No, because most kids understood right from wrong. If they didn't, they learned it with the principal's board of education and again that evening from dad's belt.
