This is nothing new.
In america, the public school I went to 40 years ago barely touched the subject of the communist mass murderers (when in reality THEIR murders and terror and tyranny made the more mentioned Hitler look like a amateur by comparison).
The leftists have done their work and the generations who know the truth are slowly dying off.
I would add these lying/fraudulent/apparatchik leftist ‘academics’ to the list of people who will be held accountable for whats going to happen in the future and what reaction it will bring.
Public schooling needs to end. Better that people stare their ignorance in the face than walk around with their heads full of garbage they believe to be true.
