Ahem, the way to cure ignorance is education. The way to education is to come out and teach what you know is true. The way this site goes that majority you mention (the heterosexual, married, crossdresser) won't come out and be counted. So who can blame society for thinking a) CD's are gay, after all don't they want guys and since they are guys that would be "gay" right? Where do you find Drag shows? Gay bars. and that b) CD's want to be women (and I would not just brush that aside as not being a significant number especially here) when TS's get more press than hetero-married CD's...who stay hidden and don't make any waves.
First step is "we" as a group have to dispel any idea that we are in anyway abnormal...both to ourselves and to the world (start with not going to see any media that portrays TG's as crazy, insane, clown like figures who are socio-pathic like Springer and almost every movie ever made about TG's). If we don't believe that what we do is not wrong then how can you teach everyone else it isn't? Start with the stereotypic rumors...like we are all gay and we "want" men. Listen to children and watch to see that they don't really care how a person dresses until we TELL them it isn't right. Own what you are. Every equal rights fight has started with the group teaching that they were NOT what the majority thought they were. And they had to say it loud and proud (sorry for stealing that).
and just as a heads up, don't be using the "women can wear what they want..whah whah" argument too much, they did as I said above and made it "ok" by taking charge of who they are. It wasn't just given to them
