I was watching a movie once, when I was younger and much stupider about politics, and it showed a coup and government takeover. The first thing they did was gather up college professors and shoot them.
I always wondered why they did this, and now it seems so totally obvious. You need them to support your side so the next generation of children gets indoctrinated correctly.
Same thing happened here in the 60s and 70s, only the Bolsheviks didn’t shoot them.
They simply harassed them until they quit — and put their Leftists pals in to the teaching positions.
