Perhaps you are in the wrong crowd. I have found that the LGB part of the "queer" community is more that willing to advocate for the Trans people. In the forums I participate in, it is the striking LACK of trans participation that I notice most, but I will concede that it has been improving slowly. I was asked about this by the Russians delegates who visited. I noted that the Trans world still remains behind the gay world in terms of public advancement, however we are ourselves to blame if we don't stand up and advocate for ourselves publicly. As for separating the branches of the LGBT community, that is exactly how we will fail. The social conservatives would love to "divide and conquer" any group that challenges their dominance.
Like you, I find men in G-strings distasteful, but no more so than people who publicly wear other fetish gear. There are sub groups in the trans community that I avoid for the same reason.
Note I intentionally embrace the term: "queer", even though I am neither L,G or B.
I believe we (and I mean EVERYONE walking the earth) are queer in that we all diverge in some degree from what would be absolute normal behavior.
