Since this topic has been going on for five months, I'm sure about every idea possible has been brought up. So at the risk of being redundant, I would still like to throw in my 2 cents...
First, I find the question to be irrelevant. Or at least it should be irrelevant. Why? Because one's life should not be defined by their label. Instead, a label should describe a life. And much of this discussion has been about defining one's life based on a label.
I find this especially scary since there are no fixed definitions for these labels. Most people (including me) have their own definition based both on their individual experience and even their T* political/belief leanings. So if we cannot agree on a label, how important can that label be?
I also note that the initial question was politically loaded from the start with the word 'just' before CD, and the implication that there are only two possible conditions, TG or CD.
OK, now to a specific comment on the label transgendered. There are a number of definitions of TG, but for me it has always been an all encompassing label. Transgender refers to anyone who transcends societies gender rules. That label includes CD's and it includes TS's. It also included a wide swath of other labels like drag queens, androgonyms, TV's, two spirits, boychicks, gender queers, she-bears, ambigendereds, etc., basically anyone else who is not cisgendered.
Note, many people don't like this definition of transgendered because it associates their gender path with other gender paths they hate, however, it is still a very common definition. I can trace this usage back to at least 1990 in some glossaries and writings, and I also note that that is how the word is used in the term GLBT which is recognized by both the activist community and many world governments.
