Kia Ora Annah,

Interesting topic BTW.......................

Slightly off topic but not by much....
Do I pass[blend in] or am I just "acceptable" ? 
Sadly it's a fact there are some trans-people who will always be identified as trans, no matter what surgeries or amount of HRT they might have to correct their
birth sex characteristics...
No doubt there are some who live in an environment/community where the majority of cisgender people are pretty laidback and
"accepting" of diversity....So even though they don't "
blend in" in a physical sense, their somewhat androgynous appearance[dress sense, long hair make-up, etc ] is
"accepted" and they are given the
honouree status of "female" within that particular cisgender community...Outside this community well that could be another story...
However, even though we like to "believe" we do....I believe
no one "passes" 100% all of the time...and in a lot of cases because
we don't "greatly" challenge society's concept of gender, we are given the
"benefit of the doubt"...
If a cisgender person pays attention to detail "anatomy" they will notice
the tale, tale signs of the former birth sex of some, for example, a combination of the following = Height, hands & feet size, arm lengths, shoulder width, etc...There are a number of things that subconsciously a cisgender person will pick up on and if these things aren't poking too much outside their socially constructed "gender identity box" they will be dismissed, hence given the "
benefit of the doubt"...
Oooopsss sorry for being slightly off topic.....
