In my personal opinion, when I hear someone complain about a guy not acting like a 'man', I don't think of gender specific duties or roles. Times when I have felt that someone was not being a man was when they were being less than honorable, shunned responsibilities, refused to care for those under his protection, abused a position of power, etc. Of course these all speak to areas where we should all strive to excel in, regardless of gender. Women just have different ways of exhibiting their more lovely qualities and have different things expected from them. For me, if my husband isn't living by what God's word says is righteous behavior for a man, then I am more apt to think that he isn't living as a 'man'. During those times he is lost in foolishness and is acting like a boy, instead of utilizing his God-given gifts to prosper mentally, spiritually, and physically. To me, THAT is what becoming a man is about, not so much a matter of hobbies or sports.
Now, as a separate issue, I believe that women of the world have been working real hard to win equality with men....and surpass them. I see that as usurping a man's position, and many women do that through bringing men down to a lower level, instead of trying to honestly better themselves. Unfortunately, selfishness seems to run rampant among many women these days, and we're complex enough to find manipulative ways to get what we want. Hey, and if that means slowly degrading men for their testosterone or seeking to humiliate men for enjoying what comes naturally to them, then it is done. I'm not saying that all women are like this. Shoot, there are some women who enjoy a man who is confident, assertive, generous, and loving. Not everyone likes a guy with a backbone that resembles milktoast. lol

Some do though. I know lots of women who only seem to love men because of the power they have learned to exert on them. All in all, men need the freedom to act like the creatures that they were created to be, and women to have the same freedom, all without criticism. Like I said though, I think that these are two separate, but related, issues.
