Let me start off by saying that the foundational premise of your piece here is so beautiful and true. I highlighted all of the parts that especially resonated with me.
In a nutshell, your piece spoke to me with this overarching message: diversity makes us stronger. Anyone who is truly comfortable with their masculinity or femininity should be equally as comfortable embracing EVERY SINGLE ONE OF US for the multidimensional creatures whom we can be (I intentionally word this to exclude those humans who thrive on their one-dimensionally hegemonic views, regardless of where along the ideological spectrum they might happen to fall).
There's one critical point I want to bring up, although it isn't necessarily a criticism as much as it is food-for-thought. The phrase "Be a man" can be very triggering to many of us (i.e. male-identifying persons who fall outside of heteronormative expectations across so many areas of our lives). It implies that the messenger has an idealized vision of what they believe a biologically-assigned man should be (philosophies and behavior), and it's a big part of why the concept of "chivalry" is so often still viewed as a monodirectional gender-exclusive concept -- yes, even amongst many members of the political Left.
I recently finished up participation in a 12-week program that essentially functioned as a progressive men's group, and, in it, we explored (via our weekly video-chats) what it truly means to "be a man" -- and how our own views on it will so often differ from what society expects out of us (whether those expectations come from self-identified feminists or from toxically-masculine people who rail against "identity politics"). It was a very powerful and uplifting space (for a handful of us dudes in our late-thirties to mid-forties) -- and I wish such spaces could be provided for younger boys and Centennial young men.
