Just wanted to post an update/rant:
I apologized to my psychiatrist for my lashing out, then asked him very pointedly what his opinion of transgender hormone replacement therapy, in case I had misinterpreted.
His response was that he has no problem with anyone identifying as their preferred gender identity. However, he believes changing one's hormones or anatomy is "unhealthy." He did claim that he has worked with transgender people who have pursued these things and is willing to work with me.
I'm just not sure that I can reconcile this... How can someone who makes his living changing people's brain chemistry using only their personal accounts as a diagnosis and evaluation believe this?!
I just feel like he is not really supportive of trans people and their gender identities if he holds this opinion. And that's perhaps what irks me more than the opinion itself. But the opinion bothers me too.
What about people born with cleft palates? Is changing their anatomy "unhealthy"? What about cis-men and cis-women with hormone imbalances? I have a feeling that he would be just fine with treating those with hormones, as before I came out to him, he even had my thyroid tested.
So if he is okay with these changes for other reasons, but not okay with them for gender dysphoria, then he doesn't really support people's gender identities.
