I think it's reasonable to understand yourself as transsexual but not transition. Based on my experience however, I have some doubt in my mind about it that is hard to erase... All the ts people I know are either transitioned, desperately trying to, or miserable. Despite myndoubt, I don't begrudge anyone that is suffering the life of a woman that lives as a man, and I think if transition doesn't happen, for whatever reason, you have the right and the responsibility to mitigate the gid in any way you can...
Saying there is some kind of tg umbrella does not make it so..So arguing the tg umbrella is somehow necessary to communicate assumes the idea that there is one....I argue that there isn't (or at least it doesn't include transsexuals), and so that it actually hinders communication... If I am job hunting, and a person thinks of me as similar to a drag queen, need is say more?
The point that this is a forum and it gives rise to disagreement is well taken... I have a ton of friends in the cd world...we never talk about this stuff, and it's just a given that we are at different places.
