Nope, Bernie and Hillary are not authoritarians. The others in the GOP race aren't authoritarians either or at least not much. Look up the description of authoritarian leadership for yourself. Trump is an authoritarian whose policies best fit fascist policies of the past century. I'm not calling him Hitler but he's very much like Franco and Mussolini. The conservative movement is dead, the tea party has taken over and they are authoritarians not conservatives. Trump is all about big government programs, mostly police programs, anti immigrant programs, and an expanded military. Oh yeah and big budget deficit spending.
As far as Democrats vilifying European Americans, well, that's not true either. Democrats vilify racists, bigots and also too they vilify authoritarians and trickle down economic voodoo shit. And rat-informants. But just about everybody vilifies rat informants, even the cops that use them.
fuck the GOP
