The idea men should express themselves combined with the limits on socially acceptable expression have always been a strong indicator to me that "men showing emotion" isn't about men showing emotion.
The social limits on expression aren't even based on a laughably bad interpretation of "heathy" expression. It straight up means to continue conforming like you always have, but additionally cry and show emotional weakness when socially cued to do so.
And you expected different? Social life is a game of shared expectations and showing you understand when to lie and not to, how to act by the rules for children and when to break them. Most moral discussion is posturing, just as most social discussion is an attempt to score political points.
