When the Democrats had control of the entire government they failed to take the opportunity to guarantee TGs equal access to housing and prevent job discrimination.
These two inexpensive things would have allowed TGs to have better lives and to integrate with others thus showing they aren't that different after all. However, the Democrats aren't going to fall on their sword for three tens of a percent of the population which is basically broke.
Sadly, the GLBT movement is generally led by people with no feel for the political process. The best they seem to be able to do is try and copy the black movement, which suffered from different forms of prejudice, and, on occasion, quote Marxist philosophy which no one takes seriously anymore. In turn, political operatives use GLBTs for fund raising and action, but they have no intention of helping them. I call it the "long con." I have taken several runs at these people, but they live in their own world which is funded by donations by often poor TGs. (Last study I read said the disabled were the number one economically disadvantaged group, followed by TGs, and then gays...)
Most people are fixated on unemployment (It would have been better to help GLBTs in "good" times.), which is understandable, plus they do not see GLBTs as part of the American fabric. (In fact, most people think they don't know any TGs...part of why coming out is important.) The tools tried so far don't address these problems. In fact, I think the only think an outsider that has helped is Oprah who got regular folks talking.
One of the problems with the parades is the supposedly sympathetic media picks out the weirdest people to show on TV undermining the whole process. Though gays support TGs and bisexuals more than straights, it might not be as by as much as you might think. When you march in a gay pride parade, you're marching for gay rights; not TG rights. Often, viewers do not understand the difference anyway. When I brought up the problem with parades and how they should be re-focused or discontinued, I get told I don't understand its "part of the culture." Yeah, so are show tunes, but they haven't helped either.
The way the polls have moved, I think TGs (and bisexuals) would be better going it alone. To a certain extent, this has happened. I was surprised with how many well know singers have come out as bi in the last year. (I've also been somewhat surprised by the non-reaction to Rhianna and Britney singing about leather sex and similar adverts.)
TGs can help themselves a lot by not being fixated on their situation and not being so narcissistic, because re-enforcing the stereotypes.
Sadly, things like this amount to slow and steady progress, though you have to be prepared to make your move if you see an opening.
