This is a laughable fantasy: it is not “Fascists” resorting to violence in the streets: the Left has a virtual monopoly on violent attacks on the Establishment, whatever they think that is: usually police and any citizen that doesn’t agree with them.
Even the word “Fascist” is a lie: there aren’t any left. The White Supremists, Klu Klux Klan and Neo-Nazis you fear are tiny groups of mentally retarded graduates of dysfunctional families; more to be pitied that to be feared.
Loopy Left-Wing nutters take to the streets, to riot, burn and assault the police, and if any citizens intervene, they must be Fascists,right?
The truth is all left-wing dictatorships are just as Fascist as right wing ones.
Hitler, Stalin, Mao, Pol Pot — all Socialists.
