It did at times feel that the term might be somewhat anachronistic. Is the term transgender preferred?

I thought, one could change his gender without changing his genitals, however, and this article was strictly about operations on genitals and hormone therapies that aim to change the externals, since the internals are just fine the way they are. A person isn't switching their gender identity, they're switching (or trying to switch) sex.

I had interactions with people from the community online, but not to any great depth. It's quite possible I'm wrong about how I approach certain things or in my definitions. But it's all based on solid research (see Nature article) and the individuals were referred to as transsexuals in the literature. But those articles, though of historical significance, are a bit old now.

At any rate, this is what the comment section is for, to correct and enlighten me!
