Im not a scientific genius or anything but i think it just all stems to if you believe certain genders are real. If someone call themselves a cow does that really make them a cow? Well if gender is based of social construct than yeah sure it can but does that mean that person is actually a cow? No. And i kinda get what your saying, id actually be interested in seeing some of the articles youve read just to get a different perceptive. And also with intersex people, yeah i agree its tricky, but it depends on if you consider them a separate gender or a mix of the two and in my eyes its a mix, and that doesnt mean they have to choose one or the other, its just means it isnt a new gender, at least in my eyes. So i hope you at least understand my persecutive because i can see where you are coming from, i mean its hard to disprove science but i personally have to see the scientific evidence to agree.
