Muffin,
Exceedingly unlikely to have any influence upon the issuance of how we're represented within the DSM. Yet, with the grassroots efforts that are gaining ground in areas such as Portland, Ore. and other places, there will someday be a tipping point that will bring this issue to a National level of discussion. Between, same sex marriage, transsexual marriage status, employment nondiscrimination, and the elimination of discriminatory exclusion of health care access for transsexual/gender people; this will be an unavoidable topic before too long.
All of these issues seem to be roiling just below the surface of awareness. Tying them together as a major civil rights issue would generate the "800lb gorilla in the room" which could no longer be ignored.
