Even after I am post-op, and that's a while away yet, I will still identify as TG/TS because nothing on earth will ever change the fact that I was born male and advanced medical care is required to correct that.
Trans, transgender, transsexual are not labels to me, per se. To me, they are pieces of vocabulary, components of language which is the only tool I have to express myself and explain what I am, who I am, what I've been through and what I'll be going through. I don't see this as political, and I'm certainly not trying to make it such. There are people of all sexual orientations who have political agendas, and how I describe myself to myself and others is my business. Others will always make it their business, regardless of my actions, words, or intentions.
Am I "out and proud" to be TG/TS? Not really. Am I ashamed to be TG/TS? Not at all.
That's my $0.02.
