Are you really though? Or is that self-imposition? You THINK you'll be marginalized, lonely, laughed at? How often do you go out, put yourself out there, for all an sundry to isolate, laugh, marginalise you?
I do that (put myself out there) all the time. And you know what? I never feel marginalized. I never feel isolated. And I'm rarely, if ever, laughed at. I can walk down the street, see from the corner of my eye people do a double take, and yet see from no corner of my eye anyone laughing at me or anyone making me feel uncomfortable, like I don't belong, or that I fall outside of what they regard to be normality, or more to the point, what they themselves would or would not expect to see on their own day out in public.
I have often found that if anything marginalises me then that is myself. Nothing more. Do I think I am wrong in presenting myself in the way that I do? Never. Not once. And more to the point, no one, ever, in my experience, has ever exhibited to me the idea that I am wrong because of how I present myself.
I will never defend myself for crossdressing, because crossdressing isn't something that I need to defend. I accept it. I accept myself. And I'm confident. If someone has a problem with my crossdressing, then it isn't me who needs to defend myself, but them who has to defend their own attitude of having a problem with my crossdressing. They are the ones who have to defend themselves. Not me.
