so you are the eternal arbiter of what gene sequences are correct and which are not? laughable
We know that 46XX and 46XY are the two blueprints, because that's how biology works. Maybe you should read into the subject instead of being morally outraged.
But the basic breakdown: Man puts his penis into the vagina of a woman, Sperm comes out and after some technical stuff meets up with the egg cell, where you are created with one copy of each of the 46 chromosomes from your mother and your father (the other one being lost). Whether your father's Y chromosome is used or not (usually) determines whether you become a boy or not. Other genetic combinations are literally results of mistakes that were made in the process.
And why is there a "(usually)" in that sentence? Well, because you can still end up being a girl for example despite having the genetic makeup for the 46XY blueprint, but that's still a result of other mistakes that your body made during your early development.
And there's no way to not call these issues what they are, "mistakes", that doesn't mean an individual is less of a person, or that we should not treat them with the same respect that we grant to any other person.
In many ways it's actually like with... I don't know, glasses. Surely you wouldn't say that a person who can't see what's going on 10 meters before them have just developed with a "different way of seeing", no, you'd say that there were some problems mistakes made during the development of their eyes.
Really simple to talk about this kind of stuff if you take the emotional bs out of the equation.
I'd like to remind people that the question is first and foremost "what is gender ?", and the consequences of said definition.
Because "is there more than two gender" or "what does it mean to be of one gender" are precisely things that somewhat need to refer to the nature of gender to be answered too.
To be honest, I don't really see where this discussion could possibly go. Outside of throwing our opinions into the thread with nothing to back them, there is not much to discuss here, as gender doesn't really have a fixed universally used definition, and can be a lot of things for a lot of people, and is on top of that is also currently in a state of being expanded upon regularly.
