Lose lose situation. They want white, normal teachers to quit.
NYC under the accursed Bloomberg led the way years ago. Conservative and older ($$$) teachers were harassed, put up on totally fabricated charges, etc. until they left, retired, or were put into the "rubber room". They represented decades of classroom teaching experience, the kind of experience you can't get in college courses. For the most part, they were also "old school" teachers who really knew how to teach the subject, not just parrot the latest libtard indoctrination blather. So, they had to go, in favor of little stars-in-their-eyes newbies right out of college. Cheaper, no tenure, so malleable to get to promulgate libbie lies.
The new black superintendent of the school district where I live told the white teachers if “ya’ll don’t like the way I do things then get another job. I want more of my kind in here anyway.” The majority of teachers in the school where he was speaking were white.
