Right. And it makes sense to answer the questions of the people whom you care to answer ... especially when your doctor, your wife, or even your best friend wants to know if you identify as a woman and wants SRS.
It would be nice if we had "shortcut words" that would describe major categories of all the people in this community to avoid getting into big long explanations (like the word "lesbian" ... it describes three things: a woman's sex, gender ID, and sexual attraction). And it would be nice if everyone agreed on the meaning of the shortcut words because it wouldn't take as many other words to describe what you do and what you want. But instead, we only have three shortcut words (CD, TS, TG) to describe a wide variety of people and motives and even then there are perpetual disagreements about what these shortcut words mean. So the use of any of these terms is rather pointless.
Dr. Harry Benjamin came up with a system of classifying CDs and TSs using a 6 point scale (CD type 1, 2, 3 and TS type 4, 5, 6) but it is not used; also he came up with it decades ago and there has been more research since then so it would need to be updated. But, if you're interested, here it is:

But to the masses who are not interested in you personally, I think just using "TG" is fine, which is what they and the media do anyway. And if some of the masses become more interested, if for example they discover that someone in their lives wishes to engage in cross-gender expression and they need to find out more about it, they will. And then they'll join the debate of what "CD, TG, and TS" means, since they'll pick one of the terms for themselves and insist that it describes people like themselves exclusively. lol
