My post last Sunday about rules for answering GLBTQ questions generated a heated back and forth over what trans people prefer to be called (among other trans issues). The exchange just confirmed for me that when I'm asked questions about trans people that I should stick only to the most basic answers and then refer the questioner on to other resources and/or people who know better. When I answer questions about homosexuality I rely heavily on my own experience and personal stories. When it comes to questions about trans people, I can't speak from personal experience.
Maybe it's a copout, but I think trans people should in general speak for themselves. That said, since "G" and "T" are part of what has become the GLBTQ movement, none of us benefits from remaining clueless about the experiences of the people who fall into categories outside the one (or two) in which we place ourselves.
By coincidence, last week I was given a copy of a profoundly moving documentary about trans people called Southern Comfort. I'm guessing that it's a documentary that's familiar to trans people (it was released in 2000), but I'd never heard of it before.
