GLBT .... why "T"?

[HejiraNYC]

I think lumping T with GLB is basically done for the sake of simplicity- these acronyms stand for the subset of the population for whom discrimination in the 21st century is still condoned legally almost everywhere, including the U.S. I really can't think of an instance where ______ group is against the rights of GLB but fully support the rights of T, and vice-versa. The common thread here is gender, the right to be the person you want to be, and the right to be with the person of your choice. You can see the howls of protest that accompanied Chaz Bono's appearance on Dancing with the Stars, even though he is now "heterosexual" in a sense.
