We have the exact same problem in academia all the way from K-PhD. This shows with immense clarity that the left is a vicious cult incapable of tolerating diverse ideas. In game-theory terms, they have reached a Nash-equilibrium with all other forms of thought and see no profit in changing their ways. I guess that means, the rest of us who love real thought and debate have to push back against the left strongly enough that they realize their position is making all of us lose, including them.
