So much here is based on personal POV. Nothing wrong with that. How could it be any other way? The original question, does passing "equate" to stealth, is sufficiently vague and ill defined as to engender pretty much what has ensued.
My own take on this will probably not make much sense to most of since my POV comes from what is essentially a totally foreign school thought. I guess what I am saying is that I am not really comfortable with the label "trans*". I did not go through my own personal hell to be anything other than just an ordinary woman.
I suppose that my experience would only apply to the young in that as noted in a previous comment, "....I also feel like sometimes there is a bit of... distance or failure of communication between generations on this one. For a young transitioner, stealth is a lot more tempting. You aren't established in your profession, you don't have a lot of history, you are more likely to be up for moving cities, you don't have kids or a long term relationship to deal with, and your chances of being passable are really high. You are also less likely to have the financial security to insulate yourself from some of the discrimination or violence, so being stealth becomes a method of self-defense."
Conversely, whereas an older transitioner might not have those potential advantages, it could easily be expected that they would find another method of "self-defense".
