For anyone who isn't familiar with him, Norm is a child of Holocaust survivors. He does not believe that the Holocaust is fake. He had S++ tier trolling and grudge holding abilities. He got fired from Harvard for bullshit "anti-semitism claims" after he eviscerated Alan Dershowitz and you can watch videos on Youtube of him nuking Zionist students at Harvard from orbit. He is basically doing a "by your logic" on this and calling out how Zinoist groups try and shield Israel from criticism by claiming that criticism is anti-semitic:

Postscript: This article was submitted to multiple “progressive” publications touting a principled commitment to freedom of speech. It was rejected by all of them. It’s a telling commentary on the commitment of the so-called Left to freedom of speech that it not only supports suppression of Holocaust denial, but also suppression of rational discussion— based on the most elementary principles of free speech—of whether or not it should be suppressed. What most amuses is that, whereas this mindless Identity Politics pretends to be defending Jews against Holocaust denial, this outrageous suppression of free speech has nothing whatsoever to do with Holocaust denial. If the integrity of the Jewish people’s martyrdom has been traduced, it’s overwhelmingly due, not to Holocaust deniers, but the machinations of Jewish organizations that have exploited the Nazi holocaust for financial and political gain. Per usual, the Holocaust is now being exploited to further an altogether different agenda. Indeed, immediately as Facebook announced its decision to suppress Holocaust denial, the Board of Deputies of British Jews called on Facebook to also suppress “anti-Semitism” by adopting a definition of anti-Semitism designed to shield Israel from criticism. But the infinitely stupid, gullible, cowardly, posturing, opportunist—and, let it not be omitted, vanguardist-totalitarian—so-called Left won’t see this, just as it didn’t see that the attacks on Jeremy Corbyn had nothing to do with anti-Semitism. Who can forget the hideous spectacle of ever-progressive Mehdi Hasan teaming up with repellant Holocaust-monger Jonathan Freedland to denounce anti-Semitism in the British Labour Party?
