I don't think it's a horrible idea even if I'm dubious about the packaging.
Loose talk about "incels" disguises the fact that there are a minority of young men on the internet who can radicalise each other into being dangerous psychos. There are a much larger number who are just sad, lonely, maybe autistic, maybe just lacking in social skills, who are treated brutally by the dating market.
Whatever the specific issues with Jordan Peterson, there's a need for Jordan Peterson type influencers who can give basic dad advice to young men who've never had basic dad advice. Tidy your room, have a shower, get a job, be a useful member of society instead of blaming everyone else.
Once they graduate from the basic dad advice stuff, there are dating coaches, male and female, who already do good business with men who have different challenges - widowers who have been out of the dating game for decades, men with disabilities, men who just lack skills and confidence. Find the right influencers who can package constructive advice to appeal to young men, and I think they'd lap it up.
But it would have to be organic. If it became a government anti-radicalisation scheme run through Prevent, it would be just as crap as every other government anti-radicalisation scheme.
