I rather suspect you didn't notice the "most". I keep in perspective the degree to which something is an existential threat, and the degree to which it is causing suffering.

Although one can make a claim that the violence-enforced dominance hierarchy and associated behaviors represent the greatest cause of danger and suffering in humans, bar none--and wow, is it bad at times, whether it's the Assyrians or Kim Jong Un--I don't think the same claim can be made about the "Man Box" in the context of modern Western society.

Compared to climate change, compared to the risk of extensive use of nuclear weapons, compared to the risk of a populist authoritarian either gaining control of the U.S. or the U.S. falling apart in a culture-war driven civil war, compared to the potential for AI to radically economically disenfranchise a majority of the world's population, compared to the challenges faced by an aging industrialized world organized around the premise of a growing rather than shrinking population, compared to ongoing war in Ukraine, Sudan, Yemen, etc., the "Man Box" in the U.S. doesn't measure up as the most dire, or even one of the most dire issues.

It's a big, important issue. Just not the biggest.
