“Human beings are more complicated than the current binary allows”

Yes. Just being aware that there IS a binary framing, and not just the physical, is an important point. The mass of men are born, live and die in a framework of ignorance and patriarchal solicitation that most don’t have any impetus to consider, unless we happen to have a strong daughter, friend or spouse with the patience or anger to make us do so. Even then, far too many men are allowed to beat it back with fists or religion.
