In your face parents!....Like Hitler said to them..."we have the children 6 days a week...who are you?"
Speaking of Hitler, does anyone remember when there was no such thing as leftist science? It was just science. There was also plain mathematics, no left or right.
Except in Nazi Germany, and the Soviet Union. Big insane asylums like that had politically correct science and math.
If parents don’t personally attend school board meetings, make a fuss and not relent until they get results, they should withdraw their children. That hits the school where it hurts: in many districts they lose more than $10k per pupil withdrawn.
Enough people do that, change for the better might be expected.
That said, I do not for a moment believe that public education is a good thing, an improvable thing, an excusable thing. I am simply endorsing activism within the system for those parents whose eyes are still sealed.
