The next time somewhat starts a thread complaining that muggles don't understand "us" just remember no two people on this board can agree what it means.
Let's be clear; the T stands for Transgender.
Here's the wiki link for Transgender. I think it sums it up pretty well.
https://en.m.wikipedia.org/wiki/Transgender
Here is what is says in regard to crossdressers.
Other definitions of transgender also include people who belong to a third gender, or else conceptualize transgender people as a third gender,[10][11] and the term may be defined very broadly to include cross-dressers.[12] The term does not have a universally accepted definition, including among researchers.[13]
Emphasis added by me.
IMO, I, as a self-described CD, consider myself to be under The TG umbrella. YMMV.
OTOH.
No. Once again, crossdressing has NOTHING to do with sexual orientation. You can be gay or straight and be a CD.
Here is the wiki definition of cross-dressing.
https://en.m.wikipedia.org/wiki/Cross-dressing
NOTHING in the definition about sexual orientation. You can be a straight CD, a bi CD, or a gay CD, and you are still defined as a crossdresser.Cross-dressing is the act of wearing items of clothing not commonly associated with one's sex.
It also adds:
The two terms are NOT equivalent.Cross-dressing is not synonymous with being transgender.
