Thanks Bob Fischer, that had to be said-- this was not one of Goldberg's better columns.  His rant about Stalinist Russia was totally irrelevant.  My guess is that the alt-right  torchlight parade with its anti-Semitic slogans really shook him up, as for years Goldberg has been preaching that the big anti-Semitic threat was from the Left.  Seeing echos of the 1930s must have been a shocker.
True, some of the antifa demonstrators, by many accounts, did provoke violence, shout hateful slogans, and even got in to  physical conflict with the Unite the Right demonstrators.  If so, that is to be deplored.  At the same time lets recognize who they are up against--a growing white supremacist movement which is proud of its history of racial violence and fascism.
