“If the description is sounding like it fits”
Where in OP did it sound like it fits?
I get the impression the guy I’m replying to is working with troubled youth. Even then, most men and boys are taught to defend their moms as a point of pride, not the opposite.
She actually doesn’t say he has toxic male role models in his life, he has conservatives in his life, who she admits are not good sex-advice-givers or puberty-talk-havers. She doesn’t say they are Nazi’s or wifebeaters or something. The assumptions I’d make from this is he has conservative trad-marriage role models, which I had too. These people teach you a distorted view of sex, but also a lot of the best male role models in my life live as conservatives.
Anyway, no I don’t really think that male role models are as important as we like to think. This is kinda a “what is wrong with our youth” take on modernity. A good female role model to a man can be almost more influential. Her being a good mom is going to influence his views on women a lot more than any dudebro with no relation to him, especially if she calls him on misogyny he may pick up.
A man who loves women has healthy female role models. That’s more important than anything in developing their views on women. And then more importantly than anything, a man who will succeed in life has an internal drive to be better, learn more, not be led, etc, and that doesn’t come from other people.
