Passing to me is not feeling "less than". What I mean by that is feeling confident in myself that others now see and hear me without questioning my gender. I spent a lot of years with the shame of people asking me, "Are you a boy or a girl". That is hard on anyone and it tears you down after awhile.
Passing is ordering in a restaurant with my head held high. It's walking in the bathroom and knowing you belong in there. Recently it's walking into a College and not hearing whispers behind my back in a class.
Passing is freedom.
