You have provided an excellent example of the point I have been trying to make.  Classical liberalism does not include authoritarian, nor totalitarian, belief.  It demands equality and the rule of law, protection of fundamental rights, and the goal of eliminating bias.  
Leftists belief includes none of those principles.  Extreme Leftists are about control and tribalist division; a blunt effort to tear apart the principles defined by our Constitution and nation.  True classical liberalism. We have seen a great many examples of this destruction over the past 150 years.
