You're misunderstanding him, he means "wuss" as in a man lacking masculinity.
Regardless of the modern worlds egalitarian views, men and women will forever be different, two different genders with typically different physical and physiological profiles, example, men are typically masculine (competitive, stoic, aggressive e.t.c.) whilst women are typically feminine (emotional, relatively more irrational, sensitive .e.t.c.), this is just the reality of the matter, unless you want to say that there is no typical physiological difference between genders?
That being said, who can teach a young boy how to hone his natural masculinity better than a experienced man of quality? Yes a women could teach her boy how to be be a good man in theory, but a woman will never understand what it is like to be a man nor what it is like to be a boy with a sht load of testosterone, that's understanding reserved for men only. That understanding we have allows us to communicate with boys and teach them a lot more effectively than women because we understand them, sht, we were them at one point.
So i disagree, a father present in the house hold makes a pretty big difference when it comes to raising good men.
Yeah I don't believe it's so clear cut like that. My father was raised by two upstanding parents, yet he wasn't responsible/accountable and ran out on his wife and let her raise 3 kids by herself. Good man?
There are exceptions to the rule, like I said, there is no guarantee, many factors come into place to form these "good men". You can have a four star badass in your household your whole life it doesn't mean you're going to be one there is always the foreign influence. No parent can keep 24/7 watch on their kids and if they do they are Helicopter parents which can be detrimental. My mother raised 3 kids by herself two boys and one girl. As far as I can tell none of us are bytch made and we don't have daddy issues. My brother is pretty much the poster child of stoic, has a competitive streak and there is no prissy qualities to him.
You're right it's healthier to have a strong father figure in the household but even his role can be undermined.
