Lana Mae, one thing you should think about critically is whether they are supporting crossdressers or transitioned trans men and women. I have seen lots of people who assume all "transgender" people are like me - cis-normative, transitioned, full-time, on HRT, surgery-bound, etc. Also note, legal rights and social acceptance are two separate, albeit related, battles. True social acceptance will take longer.
If you want CDing to be more accepted, then the path is clear. A LOT of you need to come out, and you need to start living your lives in the open. Stop hiding that you're a crossdresser. Show people that you're not a problem. Go out and live your lives. If you're constantly waiting for more people to accept it before you do that, you'll be waiting forever.
