One of Goldberg's weakest columns yet.  He rants about the evil of antifa but fails to give any concrete examples.  Instead he spends most of his column denouncing Stalinist USSR which most of us agree was about as bad as Naziism, but hardly  an analogy  to antifa.  While I agree any antifa violence-- except in self defense- is deplorable, it's not in the same league as the Nazis or KKK--- and Goldberg knows it.
Goldberg's problem is that like many advocates of Zionism he's long pictured the Left as being the enemy of Israel and the Jews, and thus was totally unprepared to deal with the sight of young  right-wing white-supremicists shouting vile anti-Semitic slogans.  
Goldberg is going to have to come to terms with the fact that   as usual it's going to be liberals, not conservatives, defending  America's Jews from violent anti-Semitism, just as in turbulent Germany of the 1920s-1933 it was the liberal   Socialists who fought the Nazis while also dealing with the flaky  Communists.
