When have the people who refused to engage in honest dialogue with people who differed from them EVER been the Good Guys or Gals?
As I have said, the difference between a Liberal and a Leftist is that the former can hear Difference without going into clinical hyperarousal and supercilious condemnation IMMEDIATELY. The latter cannot.
Leftism generally is a Mass Formation Psychotic cult whose dangerousness cannot be overstated. What is at stake is Civilization itself. What is at stake is everything good all human civilizations have built in the past few millenia. They have an emotional NEED to make despairing slaves of us all.
