Masculinity is, of course, very important to men. But I think there's an online trend of "promoting" or at least "studying" masculinity and I think the trend, its practitioners and many things associated with it are pathetic and effeminate.
I won't say anything new about masculinity - a desire for dominance; persistence; pride; maybe wisdom. But I try to imagine great men from history and I cannot, AT ALL, imagine them worrying about masculinity as such. I'm reading a book about Hassan ibn-Sabbah right now (master of fortress Alamut and founder of the Ismaili Assassin sect) and I cannot picture him thinking about masculinity.
Nor can I picture even his novices, who are described as just young men undergoing military and diplomatic training, as worrying about this. They act (and I believe, think) like normal men act (and think) around one another.
I was, however, thinking about STATUS - now, status is probably more important. I had this discussion yesterday: what if you have healthy self-esteem and you are in order but your social and sex lives are not in order. You seem normal, decently risky, etc, but -- people aren't thrilled about you. Now, sure, you can treat it with indifference (which I guess would be masculine) but then at the end of the day you'd still be by yourself as opposed to partying with fun, sexy people. I haven't thought of an answer to this yet.
