I didn't actually vote because I'd feel like a dick voting yes, but I try to be proud of whatever I am. If it's something innate (i.e. gender, skin color, birthplace) then I'm pretty careful with my pride, and if it's some trait that's a choice or a result of my choices, then I keep in mind that things may change.
So yeah, with quite a few reservations and caveats, I am proud of being transgender. I'm also proud of having all my teeth, and proud that I can curl my tongue and cross my eyes.
