The idea that all anti-trans sentiment arises from the fact that, as transgender people, we “transgress binary gender norms” does not resonate completely with my personal experiences. As a somewhat eccentric kid, I was given plenty of leeway to opt out of boys’ activities and to cultivate an androgynous appearance and persona. I was sometimes teased for being different, for being an atypical or unmasculine boy, but it was nothing compared to the venom that was reserved for those boys who acted downright feminine. And now, as a transsexual woman, I find that those who wish to ridicule or dismiss me do not simply take me to task for the fact that I fail to conform to gender norms - instead, more often than not, they mock my femininity. From the perspective of an occasional gender bender or someone on the female-to-male spectrum, it might seem like binary gender norms are at the core of all anti-trans discrimination. But most of the anti-trans sentiment that I have had to deal with as a transsexual woman is probably better described as misogyny.
