I don't get how any TS can exercise a special trait if they've spent 10 or even 20 years living as a women and transitioned in their 20's, unless they've had no social contact with any women or men for all these years. Even for the others, many had a good base of socialisation since they never really integrated into male society and absorbed female socialisation (without being able to use it); that's my case. I had a good base and picked so much more in just one year and I bet this will continue in the future.
My sister is 5 foot 8, considered pretty but has more male traits than most men I know, she's more aggressive than 3 other guys put together and runs an entire department at 32 years old. Her 6 foot 2 boyfriend's got more female trait than her. But as far as I know, she's no man (that I know... Since I don't have "the power"... ).
There are older transitioners that don't get rid of their male socialisation very easily and don't pick up on female socialisation easily either. But, these are not the majority of TS after a few year of socialisation, unless you lump many GG into the TS realm (hey, they didn't know they weren't really women... )
The point is as always, why care so much!!!!! The fact that someone can believe they can discriminate absolutely any TS is something I can't fathom. My opinion is that this is way too much attention spent on looking around for clues that point to nothing but our own insecurities, and says nothing about the person in front of us.
I'm in no way unpassable, but I do get hastled in around my house because they knew me before transition. So, I'm living the unpassable life around my house while still passing, oh the irony of this. Still, its only when I'm being followed and yelled at on the street that I feel the weight of this. That others are uncomfortable (because they know I was a man before because they know where I live) I don't give a crap, its their own problem; as long as they resolve their conflict internally and let me live in peace, I'm happy.
