I talked about this on the old site when something similar came up (moreso about the radicalization of young white men) and I'll see if I can dig up some of those posts still, but the nice guys/incel/gamergaters/alt-right guys really have no insight at all into their issues. I mean, take a look at any of the underbellies of the incel forums and you'll see clear bitterness and talk about how they're incel because of their asymmetry, facial structure, etc. but at the same time, they'll openly mock fat girls, girls with acne, etc. They project outward and blame EVERYONE except themselves for their situation. Now to be fair, some of it is conditioned with societal norms and pop culture and so forth. Media has conditioned men growing up to believe that they're the hero of their own story; that they rightly deserve the hot girl and when it doesn't come to fruition, time and time again, it just goes to reinforce the notion of "what's wrong with everyone else?" It's essentially what Peterson is saying here; it's not the guys' fault that they can't attract a woman, it's the women who should take one for the greater good of society.
Part of the problem is that say someone in that community does try to "better" themselves, the majority of the time it isn't to actually make themselves a better person, have better self-worth and so forth. Everything is done with the goal being "get the girl" and all the betterment is seen almost like raising stats in an RPG to make themselves better equipped to handle the social situation. Girls like guys that work out? Do that. Girls like guys that dress well? Do that. Girls like guys that have interesting hobbies? Do that. But a though such as "you know what, I should take better care of myself... let me start exercising to feel good" never crosses their mind. And the thing is, women (and men for that matter) see right through that. And when this shit doesn't work, it just drives them further into the incel group-think of "fuck everyone else, it's their problem, not mine."
