Why everywhere I post arguments come to live?
I agree with most of what Sarah said, we shouldn't enforce ourselves on other, like someone else said in a post, it's hard to change people's thinking of "if it walks like a duck, quacks like a duck, it's a duck", people get hurt from it and I doubt it's wise to say "They are wrong" just because someone decided to place a fact which is defying all of what is normal.
And even if people "accept" you, that's WORSE! you want to be YOU, for them you'll, even if unconsciously, maybe be "this, no this.. that's right", or even worse, you might be "that who acts and wants to be .."
If you have the look, no one needs to accept you, you are just you.
No second thoughts, no embarrassment, on top of all, you look in the mirror and see reality, if you have the wrong face, I am not sure what kind of a person you might be if you don't cry at your reflection.
But in my opinion, you don't need society to tell you the truth, most people can just look in the mirror and see it, if not, they either got there or set themselves a bubble.
It's not JUST about looking beautiful, it's about look FEMALE instead if MALE.
It's a WHOLE different meter, the beauty and the sex and people tend to confuse it too often.
Now, most people won't act like that, rather just come and ask for the bathrooms or something,
But directed to the wrong one, even that simple scenario (not from the youtube which is all humor. but the simplified one) is a reflection, it's reality telling you "you might be happy, maybe not, but you and reality definitely have some fixing to do.
It can hurt, because you are not seen as who you are, even if you WEREN'T expecting to be seen, it can hurt for many reasons.
And if you correct then "sorry, the men's room? I'm not a man" (the most gentle way I could think of), let's just say usually the guy directing you would probably think you reply is weird, maybe try to look twice, maybe ignore his feeling and correct himself anyway and keep being "

" maybe be rude.
