Last night I was at a gathering of a South Asian LGBT organization, with a panel discussion on transgender in Desi culture. It was preceded by performances by two drag queens and a butch boi comedienne, who then sat on the panel and were joined by a transsexual lady.
One gay gentleman in the audience posed the usual question we always hear: "Why do you have to change your bodies instead of just being happy with the body you got? Look at me, I'm a flaming queen, but I don't want to change my body. Why can't you just be flaming queens like me?"
The Indian and Pakistani drag queens tried to answer for transsexuals, and completely failed, since it was clear they don't have a clue either. They are not taking hormones or changing their bodies either, so they can't explain why transsexuals do. Likewise, the Sri Lankan Tamil butch boi lacked insight into transsexualism, though she can speak well about performing comedy in two genders. The Pakistani transsexual woman there tried to explain, but she lacked the eloquence to do more than mumble vaguely about "feeling." Meanwhile the drag queens, who are used to performing, were more than happy to offer golden-tongued oratory about a subject they don't understand, getting it wrong. It was frustrating to watch.
Finally another gay gentleman with better consciousness on LGBT issues spoke up and explained what transsexualism is really like for those going through the experience: the extremely painful contradiction between body and self that began in the fetus. When asked about why they used a cross-gender expression, the drag queens said they enjoyed the freedom, the pretty clothes, and the "performativity" that Judith Butler wrote about in Gender Trouble. I was thinking, geez, to me it's a matter of life and death, and they care about pretty clothes and performing. I wish transsexualism had been better represented.
So to those who argue that all "transgender" people are the same, I say no. To be transsexual is a specific burden that you can't understand unless you've lived it-- or unless, as the learned gay gentleman demonstrated, you've made a special study of it and listened carefully to TS people's experiences and insights. The umbrella term "transgender" covers such disparate types, it doesn't really convey much useful meaning, and it poses a danger of obscuring the issues and needs of specific groups.
