I think I was very clear when I said: "XY sex-determination system is based on the fact that the chromosomes one has at birth cannot change naturally throughout their lifetime, so magical or hypothetical scenarios where chromosomes can be altered doesn't align with our current scientific understanding", if people manages to change their chromosomes I guess the sex-determination system would probably change but we don't live in that magical world so things are much easier (yeah!) >However the claim that you must have 5 fingers to be a human is! This is what the XY sex-determination system is based on No idea what you're talking about ahah, people with a congenital condition are still human and no one said otherwise.
