I haven't read every single comment on this thread, because I had to work today. So I'm fine with conceding your point about transgender vs transsexual.
I also admit that as far as I'm aware, the number of transvestites and drag queens who identify as transgender is rather low. Higher than the general population, perhaps, but I really have no definite data on that. It's also true, however, that not all trans people experience significant dysphoria. That's neither good nor bad. It simply is.
What concerns me most is your hostility to the LGBTQ community. Yes, it's certainly true that our activism has frequently failed trans people. Particularly where the HRC is concerned, time and again the trans community has been thrown under the bus in the name of LG rights. (Bi people also seem to get shafted, though maybe not quite as much.)
But who else is even trying to do the necessary work? Originally we were all put in the same box because straight cis people found us all freaky and weird, but some of us actually do believe in solidarity. For every judgmental "drop the T" white twink or TERF, there is at least one person like myself, who wants nothing more than for everyone to be acknowledged for who they are on the inside. LGBTQ people aren't monolithic. Plenty of us want to listen and help in whatever ways trans people feel they need most. I hope you understand that.
