I don’t think a counter-argument needs to be difficult, well-researched, or even informative in this case.
Jordan Pererson’s apparent thesis is that the holocaust never happened.
Follow his logic to its conclusion. Jordan Peterson suggests the holocaust was wasteful; he thinks instead the Jews should have been enslaved to power the war machine, and then exterminated later on (which, of course, is what the Nazis actually did, although Peterson is either unaware of this or has deliberately chosen to deny it). Peterson suggests this failure to economically exploit the victims of the Holocaust is partly responsible for the Nazis’ defeat. In his professional opinion as a Jungian half-wit, we cannot estimate someone’s intentions any way but by looking at the outcome and assuming they intended for that outcome. Therefore, by prosecuting the Holocaust, the Nazis intended to sow death and chaos (mark of cain) and specifically they intended to lose.
Which is just reductio ad absurdum. Obviously the Nazis intended to win (i.e achieve their stated goals, even per the above Jungian horse**** they must have intended to complete the outcomes they had previously achieved). However, the Holocaust implies they intended to lose. Therefore the Holocaust never happened.
So is he a moron, or is he a Holocaust denier? Well, his fans sure don’t think he’s a moron.
