I actually agree with half of this. The last line for example:
"Rooting our social possibilities in our bodies is an abandonment of our humanity in favor of mere anatomy."
Surely this is women's lived experience throughout the ages? Being defined by our bodies, and our childbearing ability?
The idea that it's women standing in the way of trans people's self-actualisation is an extremely impressive extension of humanity's ongoing misogyny if you ask me.
The problem is the the body is a fact. I can't get away from it. No amount of argument or verbal definition has ever convinced any organism to be anything other than what it is. A biological entity with one purpose: to reproduce itself.
