Oh but hang on, how comes a bit of tech is allowed to assume gender (if it worked), but people aren't?
What next, complaints because a chromosome test shows the correct xy or whatever?
It's like saying I'm blood type B, but I identify as A+. And as we know some blood groups cannot accept certain blood (I forget which and too lazy to search).
Call yourself what you want, but you have to face the reality that sometimes you have to suck it up, and some things will be based on your sex, biology or whatever. There's no getting away from it.
Even if say face recognition was done to go from head to waist, it still wouldn't work. Even putting aside for one minute that not all females have visible breasts, how would it separate women boobs from manboobs 🤣 Even facial hair isn't going to determine. Although I suppose it opens up that hated question - what physical features define a man/woman. Because realistically until this can be done, sex will always be assumed by the tech. I don't know about others, but I don't what tech that can think independently.
At some point in our lives, we have all been called the wrong sex because an assumption has been made. Adults deal with it and move on, a child might take offence for a few moments, and it's forgotten.
