So it's because they remind you of Real Life men that you don't like? That makes sense.
I assume by "barriers" you mean things like "MEN HAVE NO EMOTIONS EXCEPT ANGER." Which, yeah, is pretty irritating. One of the ways that guys get screwed over by patriarchy. (Even though crying used to be a sign of INSANE levels of manliness, according to Cracked.)
Anyway, uh, I dunno. There are ladies that do that, too, just probably not as many. Sara before she realized she was gay would be an example, I think.

Sure, the first guy to show weakness at his job is more likely to get passed over for promotion or maybe get the shit jobs handed to them which can lead to getting fired, etc. etc. Thereby jeopardizing those he supports. Vlad Tepes (and this actually is from my wife, not me) was a nice guy by some standards because he did what he did to protect his people and because he was up against a superior force, had to do it through fear. He's regarded as a folk hero in some circles.
Showing emotion in general is a cry for help, a plea for comfort, help comes from others which is a burden to them and most guys like to be the providers not the helped. Action not reaction. Solutions not contemplation or commiseration.
Then there's a completely different level where women generally are unwelcome of certain kinds of attention these days...sexual harassment suits and this and that so there's another set of feelings to keep a lock on.
Some good clean anger is something that can help you get out of bed and deal with all the rest of it instead of getting under the covers and sucking your thumb.
