I have come to realise that part of the problem here is that people like me, who transitioned early, were relatively lucky with physical appearance and voice etc (partly because, as I later discovered, I am actually Partial Androgen Insensitive) often decided post SRS, to go stealth.
For about 20 of the last 30 years I would have defied any of you to have picked me out as Trans. In fact in the UK I was often on TV, the radio, and I even once went to a Trans club with a friend who is a doctor in that world, and as far as I know, no-one got me!
But then it struck me that it is actually not only dishonest, but also slightly disrespectful to the cause. So I outted myself - and since then have been openly trans.
My observation is that people treat as they find. If you come across as ordinary, relaxed and comfortable in your own skin 99% of people are fine with it. The secret is not to try and convince people of what you are - instead just be it!
And yes - I think, in the UK at least, we are becomming a lot more accepted.
