I urge people not to hitch the wagon of trans rights to the idea of inborn, dyadic, neurological differences. Brains are extraordinarily complex and shaped by culture and experience over time. Gender identities are multiple, gender roles constantly evolving, and gender expression varies widely from individual to individual. Intersex people face huge obstacles, and framing us as the lucky group to be emulated denies our suffering. The solution to transphobia is not neurology, but political activism.
