Have to agree with Shining Star here... the concept of a true TS being someone who will do 'anything' to achieve the desired gender is just not a good standard. One of the measures used against trans folks of all stripes is how few trans folks go on to lead fully transitioned lives.
We need to remember that trans is just one slice of a person. It's a very important slice, but it is just one aspect of their lives. If you have enough other pressures, fully transitioning (or staying transitioned) may not be the best answer.
Right now they are using the limited number of folks who fully transition as an excuse to push therapies that 'correct' folks who would transition rather than recognizing that the majority of folks who have the condition will not transition due to societal, family or economic pressures.
I personally know at least two folks who have pursued their transition just enough to not feel horrid when at home in the shower. They know they could not be fully successful in the real world as a trans person, and fear poverty and being banished from society more than the discomfort of boy clothes to cover their changes.
Dr Phil had a couple of shows on dealing with young folks transitioning... and repeatedly quoted that only 15% of folks who show this condition young go on to live trans lives. My mom looked at me and said 'see, only 15% really have this disease.'
I had to point out that the number wouldn't include the folks who suicide, crossdress (without the sexual component so often derided) and/or live through fantasy lives. It wouldn't include folks who live in areas where there is no help or information available about the condition.
Anyway... just wish we wouldn't continue to disown someone from the family who does not charge down the lane of full surgical transition at any cost. Some of those who don't are no less trans, they just have other things in their life as important at that time.
Most trans folks don't transition when young... because their family or financial situation don't allow it. We don't look at those folks as non-trans because they wait until their finances or family situation allow it. Why do we look at adults with all their pressures and say 'if you were really TS you'd have transitioned by now'. Do they not have financial and family pressures? Can they not plan their life to be who they need to be when they feel it best?
Sigh...
