I think a good question to ask is: "WHY is it important that young men sit in classes and approach real women?"
(Btw, I'm not defending these men at all; hear me out)
An unsatisfactory answer would be: "Because that's the normal thing to do." But why is it normal? "Because everyone else is doing it."
A more satisfactory answer would be: "Because long-term, doing those activities will result in more personal growth and more life satisfaction than watching porn and playing video games." But then you have to ask if that is actually true. Certainly for some people it is better to have a higher education and to get married. But realistically, for a lot of people nowadays, education means nothing but crushing student debt and approaching women means nothing but the depressing reality of having to deal with obnoxious women who are entitled and pampered and think the universe owes them everything.
Faced with this reality, I can empathize with men who choose not to live the 'normal' path. But at the same time, sitting at home all day watching porn isn't a good life path. There is a third way: Following your passions, taking up challenges, making up your own rules and living life your own way.
