Humans, (not “men,” not “women,”) often channel emotional pain into anger, especially when they’ve been told by society/those around them that they’re not supposed to have, or show, emotional vulnerability.
It’s a remarkably ill-informed and destructive, yet somehow still persistent, belief in society that men aren’t supposed to be as “senstive” as women. Traditionally, this belief has simultaneously cast a “feminine” show of emotions as hyperbolic or frivolous, and a “masculine” show of emotions as being steely in the face of hardship, or unaffected, or aggressive, etc. Both castings are nonsense. Both castings are harmful. (From my own experience, I’d say we’ve made more progress dismantling the former, and notably less progress dismantling the latter, which is frustrating and unfortunate.)
Men and women just aren’t that different. We’re all, first and foremost, humans—and we all traverse the same pyschological landscape, even as we each (as individuals, not genders) develop our own “maps” to guide us through it.
