I generally agree with him about our image of ourselves. We shouldn't need to hide, and I'm as guilty as anyone of feeling like I'm not a genuine woman if I don't pass.
However, I think he's putting way, way, way too much on the word "passing". That word is not what's causing the issue. It's the fact that for most people, seeing is believing. Our brains are wired to gender people (procreation of the species sort of depends upon it) and unconsciously people gender other people.
Take me, for example. I'm a transgender rights activist. No one believes more than I do in our right to be seen as who we are. And yet there are trans women that I find myself gendering as male no matter how hard I try not to because something in their presentation fires the "male" neuron in my brain.
