Good work-- and brave work. It's hard enough to watch and think about that I suspect you may not get a huge volume of response. But I think those people at watch it will appreciate it, even if they don't all respond.
And, what makes a man? Only answer I have is that a man makes himself. Sounds like an evasion but, to me, it's not. Gender identity is core; you know what you are, and that's really the only thing that matters. Anatomy, genetics, and hormones are related to gender identity, but not the reason for it-- correlation isn't causality. Social gender roles are about control and conformity. Yes, some people find meaning and joy in enacting their gender in a traditional way. I respect that, even if I don't really get it. But once you step off that path, and start asking the questions instead of taking the answers for granted, you're writing your own story. Each of us has to define what being a man-- or woman-- means to us.
For me, it's looking life in the face and not flinching, seeking the truth and speaking it, using the gifts I have to help and protect others, caring for my family, loving fearlessly, finding and making beauty and joy, and doing my best every day until I'm done. That's who I've always been and, for me, it's being a man. I appreciate seeing other people's answers, and I love it that everybody's answer is different. To me, gender is a Mystery, something that is understood only by experiencing it, something that words can only approximate, but not really explain.
Your video is a really well done piece. Well written, well thought out, and well presented. You've made meaning from your suffering, and turned it into something that can move other people towards understanding. That's no small thing.
