'nothing passed xx and xy'? Did you mean past? Frankly you are just displaying your ignorance here. First of all- there are certainly other combinations besides xx and xy- there is also xxy, xxyy. There is also hermaphroditism- which is not likely genetic but happens during development. And of course there are a whole host of things that can happen during development- and even after birth(Hormones control lots of aspects of sexual development)
There are also people born with three arms and other deformities. Do we call them "normal"? No, we call them "deformities" or abnormal. You don't reinvent language because you have a weird sex addiction. Nearly all LGBTQs are normal xx females and xy males who have adopted behavioral abnormalities. The males like to use each other's assholes as artificial vaginas (closeted heterosexuality) and the females like to use dildos (closeted heterosexuality). The status of LGBTQ is all in the mind. Mental abnormalities and habits and dysfunctions don't get special class status. Because if one set does, they all do. That's how equality works per the 14th Amendment.
Left handedness is not "normal"
Having blonde hair is not "normal"
Blue eyes are not "normal"
The key is that those conditions do no harm to society and are accepted. A persons sexuality is their own business
Left handedness is "normal"
Having blonde hair is "normal"
Blue eyes are "normal"
Believing that your normal body has no arms or legs is not "normal".
Believing that your normal body is blind is not "normal".
Believing that your normal body is deaf is not "normal".
The condition of not being normal is called Body Integrity Dysphoria. The condition of not being normal is also called Gender Dysphoria. Neither are normal. A Dysphoria is a disorder. There is no blonde dysphoria or left hand dysphoria or even blue eye dysphoria.
A person's sexuality is their own business EXCEPT when they demand that YOU or I agree with their disordered belief. A man who believes himself to be king, might demand that his subjects get on their knees but so far, there's no law making anyone do that.
Next up, "cotard's syndrome". We will have to accept the assertion of people that they are dead and we must start removing their internal organs.
