Yes! Nice to see someone here has taken the time to educate themselves about gender identity and have understanding and compassion. Good for you, fuzzybuddy!
But then there's the public perception side...
I agree that any given individual may have an "identity mismatch" so far as being comfortable with their *******ia. This is entirely understandable, but it's only half of the issue, the other half is that the remainer of the public also sees this person, and by long engrained visual cues identifies them as male or female. Since there is no real biological concept of reproductive "heat" in humans, sexual identity has been mostly visual since we started walking upright.
So this is basically hardwired into *everyone else*. Even dysphoric individuals--those who do not feel in concert with their sexual organs--recognize others they see using these same ingrained observations. Without the ability to make this reproductive judgement humanity would be largely unable to reproduce enough to avoid extinction.
So it's how an individual appears, which is at least half of the equation, and if a male individual who is uncomfortable with his reproductive organs wants to portray himself as female, but sufficient visual signals send "male" to most casual observers, they're still going to tend to call him "he".
A good example is the seniors' favorite TV show (I'm kidding, maybe), Jeopardy. A recent longtime champ, Amy Schneider, is a man who is more comfortable as a woman. She seems like a nice person, likable, but within two shows I was telling my wife that "Hey. I wouldn't be surprised if this is a guy. Sure looks that way to me."
But I found I was willing to call him a her, and wondered why that was. It came to this.
Amy Schneider seemed likable and sincere and upbeat enough that it would be a cruelty to insist on calling her "him". It was clear enough to me at least that she was male, and she was not snarkily trying to force me to accept her self-identity (not on TV, anyway) so out of a sense of pity, essentially, calling a him a "her" in this case felt about right.
I viewed it as similar to listening to a little kid talking about a pet dog that you know for a fact was run over by a truck, referring to the dog as having "run away". It's not in me to force a reality check in those kinds of situations.
