Probly 'cause I'm still young... but I find the world almost stifling in how much it almost demonizes much of manhood.
Not likely an answer you're going to get from most INFJs...but probably just because I have the detached/calm/emotionless part of it down pretty naturally, so I don't feel forced into those stereotypes at all. I think I can make my case for it, though.
Skim through the TV and look at any male figures in most shows. At least a few years back (I haven't watched much tv, besides anime, in a long while), if it was a family sitcom it was almost guaranteed that the dad was some sort of bumbling screw-up, while his wife held everything together. The Homer Simpsons, Peter Griffins, Tim Taylors, and Ray... Ray... damnit, I can't remember his last name, but the guy from Everybody Loves Raymond, fill the airwaves with bumbling incompetence and virtually always have to apologize to their wives (who never seem to make any mistakes) constantly. I know there are a few other shows like this too, but I can't remember their names anymore. It was extraordinarily annoying, though.
Parents and schools also seemed extremely anti-aggression. My elementary school adminstration seemed to pour all their attention into trying to make school a nice/"safe from bullies" atmosphere--not that they were great at it, of course, but that was kind of their stated goal. We were also told pretty much always (by faculty and parents) that violence was never a proper answer. Sports are also looked at as a kind of stereotypically "dumb" thing to do. Even though professional athletes make more money than almost every other profession, it's kind of engrained into our minds (an an episode of Fresh Prince of Bel Air comes to mind) that people should only use their athletic ability to help pay for college, where they can get their education and therefore have something that's actually "valuable"--because physical shape or skills just aren't worth anything for whatever reason. Similarly, a lot of the "typically immature/dumb" things that people do for fun get attached as stereotypes for men, even when there's nothing particularly masculine about it. At least, it's always seemed like that to me. A good example of this would be binge drinking, which sticks out in my mind as a general frat-guy stereotype, although I can't figure out why. From what I've seen, I'm pretty sure both sexes enjoy a good drunken outing in roughly equal proportions.
If I were to be honest.... I think this traces back to the days where women virtually always stayed at home and raised the kids, in centuries past. Without the balance, kids were taught feminine values, which they then taught to their kids, etc. The reason I started this post with "might just be because I'm young" is because my parents held onto treating me like a child faaaar past my time, and as a general rule men don't like being confined. So some of the (probably pretty clear by this point, if you're still reading) resentment I have over this is because my desire for adventure and some danger has largely been squished under the "gotta keep him safe, because that's a parents' duty" sentiment--and I do think that restless/adventurous spirit is a typically male thing to have. So keeping a child safe by denying them choices stifles young men in two ways.
So coming from a youngish male who grew up in a safety-first home in a country that seems to idolize dealing with things in a feminine way, I would describe being a modern man as: highly frustrating.
also: I don't think we've talked much, but this is a really nice thread. I'm pretty amazed with all the unique discussion topics I've seen you bring up in all my time here.
