Evidently my last sentence? I don't disagree, and might have put it better, not said it, and so on. And it's not what I was saying. I'm cursed with trying to be thorough and saying too much or stating the obvious, perhaps making it sound more than it is, or overly complicated. So to clarify, "I never said that!". If it was referring to something else (as well), didn't catch my eye but maybe reading too much to it?
So, No No No, that is Not THE reason, merely a side note and A reason to try not to be in-your-face obvious when you (I) can do better, and not ask trouble from any inclined to give it. Like I said I like to look my best, and - yes - being if not my best, the best I can bother being, as myself, to feel as good as I can about myself. Not that I really need to pass that much for the general public - I'm not that close to the ts side of the spectrum - or am scared not to, it's just nicer, for me, to have that too, to the extent that it happens. I, too, do prefer to pass as a woman, but the main reason is because it feels better, me being more of a middle-ground tg than cd.
Avoiding trouble and unrest - obvious if you don't like fighting, needn't be said. This is a sensible wish, not the goal and main focus. The trouble can be a salesclerk giving you a disapproving look while otherwise doing their work. Unrest can be noisy kids being a nuisance to everyone because they saw something they don't notice every day. Not something to be really afraid of or stay home over, probably won't even happen, just saying it's nicer if it really doesn't - thus "prefer", not "required to dare set foot out". Then there's that tiny possibility that's less than slipping in the shower (well, depending on where you are) of something more serious, also better avoided. "Passing" meaning passing without incident, not "passing as a woman (at closer look)" (though I'd prefer that too). For this sort of "passing", like Wildaboutheels pointed out, good, normal, sane behavior mostly does the trick, whatever you pass as based on looks.
