I can only speak for myself, but it isn't about "passing" for me. All that really matters is that I am treated with the same courtesy or civility anyone should be treated with. If people laugh or talk after I passed by I won't know and don't care (or try not to). I used to get self-conscious about laughter (even en homme, because I am pretty nerdy), but I've tried to convince myself that if I'm going to imagine what people are thinking (because I don't read minds) then I might as well imagine that it's good stuff or at least that it's nothing to do with me specifically.
For those who live full time and do want to pass, I think that's more about being seen as and treated as who they are, no?
