They're transgender who want to become of the opposite gender. Gay people don't want to be anything different than what they are. I don't see a comparison here. You mean somehow a transgender wants to become a man who wants to feel like a woman but still want to stay and look like a man? We're getting into more niche territory at this point. If they don't want to do it, then it's not anyone's problems, to be honest. Regardless, it doesn't have anything to do with how the world should treat transgender people which is a non-issue, nor why I should care what their history is. In a non-judging society, I don't care what you are, you don't have to tell me, I don't need you to tell me, just like I don't need you to tell me what color of your skin is. Changing or not, it's still the same issue.
What I meant is that it seems like we're suggesting that the only way for transgendered individuals to be accepted in an idyllic ME future is for them to have all undergone gender-reassignment, rather than always having been accepted for who they are.
The comparison I was trying to make, to say, a "cure" for autism if it existed in ME is that even if someone chose to undergo the procedure to fix something they considered "wrong" about themselves, that shouldn't mean it is a necessary requirement for people to accept them. Trans who've transitioned and trans who haven't shouldn't face different types of treatment whatsoever, nor should those someone neurotypical be treated differently than someone autistic, especially since the NT in this scenario could easily have been autistic yesterday?
If we really wanted to highlight that the society in ME have grown beyond such prejudices or put in contrast with how it was presented in DA, then regardless of the status of the trans individual in the game, it would probably best be served by being something none of the characters ever feel the need to comment on... because why would or should they, it doesn't matter?
If the trans character does want to address it, then why shouldn't they either, why must the writers be prevented from letting a character tell us about themselves because some might complain or accuse them of putting this character on a soapbox to carry out some PSA?
I agree with you though, for a society to truly have no judgments, the correct response to anyone attempting to raise some imagined issue regarding religion, race or gender identity should always be a resounding... "And?"
