David Horowitz likes to write on ways in which conservatives are systematically excluded from the teaching profession.
A response to Mr. Horowitz provided a very interesting insight into the fascist mindset of progressives. In support of ideological litmus tests in schools hippiepooter said: "it is you who excludes yourself from the employment."
Progressives are such ugly people. They will design a system in ways to exclude people, then cast dispersions at the people they exclude. "It's your fault that I am doing this horrible thing to you."
Sadly, progressives are so full of their own self-righteousness that they can pull these things off without rebuke.
