Hi Lucy. Yes, I HAVE heard of the Art of Manliness website. It's very, very cool. I came across it a few years ago but didn't keep up with it after a few months. I remember at the time that I loved it and when going back to look at it, I remember why. It discusses things about being manly without being completely misogynistic.
And there in lies the rub about manliness and the millennials' changing definition of what manliness is. How does a male be manly without being an affront to women? I mean, those qualities and behaviors that Exris described are not exclusive to alpha males or men. Women can exhibit those traits as well. It just makes them just as much of an asshole as if a man does it.
With that in mind, I came across an article that, after the PhD psychologist offered her analysis, ended with the question, "Are men being feminized, or are they being humanized?" I think it's a valid question especially if one accepts the idea that masculinity or femininity are social constructs.
