Ernest has a point, though I doubt the trans community with agree with it. Most of the people frequenting and supporting drag clubs (which most people would think would slowly disappear, rather than growing) fit into this category. They initially work in the clubs in an effort to earn money for their transitions, but then decide they like the community and the gay men who support it (I've always had issues with gays who favor these women, as it appears like they're in denial about their sexuality, making love to women with dicks rather than recognizing they're attracted to guys).
As such, I'd consider the 'shemale' community as a subset of the trans community, who are, more or less, in open conflict with the greater community. The one side is trying to remain under the radar, gaining acceptance by the wider community, while the other is trying to promote how extreme they are, garnering anger and freakish curiosity by the straight community. It's much like the blacks who insisted on being called "Negros" years ago as the others in their community argued they needed to change the language of the race-relation discussions.
Note: All of the above are my personal observations, and aren't based on any real experience in the community, just suppositions by an interested and uninformed outsider.
P.S. We also used to have several trans writers here at SOL, but I haven't seen them for some time. From what I've gathered, they've done like the gays have, drifted to more welcoming sites, or publishing independently rather than trying to gain acceptance by sites not dedicated to them.
