There's a wonderful bit at the end (it starts at about 15:35) where Sam articulates his hopes for the future:
Now, in my dreams, I don't foresee a society that is gender-blind, but I do foresee one that is gender-creative. Where people can figure out who they are and be themselves, exploring what that means, and in that they'll be supported. Where questioning one's gender won't be shunned, but an expectation. And where realizing that you don't fit into this gender mold won't lead to isolation and depression, but will be a source of celebration. And above all a society where people, regardless of their gender formation, are safe.It's sad one even has to mention that last bit, but Amen to all of it.
