Not to seem like I'm defending Peterson, but for the sake of objectivity I wanna comment on a few things with your post.
If I'm correct, didn't enter a coma because he got worse, that was the plan all along right? That's simply a treatment method. Also, he had undiagnosed pneumonia before he arrived there which I believe complicated things?
How do we know Mikhaila's bit on the side is a Stalinist? Hard to know if it's pure conjecture or if there is a solid basis for that label. And if he is, what's the point here? That he's brainwashing her to kill her dad, or something similarly absurd?
And just a point of curiosity, what's this about her overtaking his social media? I'm not clued up on that.
I think Peterson is first and foremost an eccentric, the all meat diet is highly eccentric behaviour and to be honest it's probably dangerous that he's preaching about it. Secondly, it seems as if he probably has deep issues underpinning his behaviour. Labouring 14 hours a day doesn't seem like mere 'highly conscientious' behaviour, it's probably more an emotional escape, maybe he's in a permanent state of crisis. The theme of escape seems to pervade his life, as can be seen in his addictive tendancies which appear to be intense. I don't think either of these things invalidate his advice. Even though there is a funny irony to his 'get your house in order' idea with his current situation you are still allowed to agree with it.
