To be fair to Peterson knowing about the downsides may be sufficient knowledge to oppose it. I don't need to know the tripe about Nazi racial theory and Lebenstraum to know they are horrible people to be opposed and even neutral acceptance is an unacceptable position - their lengthy list of travesties and failures is good enough to say "it is not only a horrible evil but an ineffective one". Even if ignoring morality they aren't an effective model. Not that Nazism and Communism are equivalent. The later at least has some non-evil implementations - there is a wide difference between unironic Stalinists who see murdering anyone slightly better off as a solution and those who think "Hey we can try to provide a good standard of living with worker owned cooperatives". Even if the latter is doomed to failure it is in no way equivalent to Nazis or even Stalinist "cousins".
