Where else in science is 'disorder' denoted as something desired, optimal, healthy, etc?
Where is the scientific justification for calling it a disorder? Just because some scientists somewhere used the term disorder to label something, does not equal a scientific justification for it. Scientists are just like anyone else when they mirror cultural prejudices by using such labels.
Desired, optimal, healthy according to what objective normative standard? Does science qua science have such a standard? Please give the source for that, that would be interesting to read.
It may be a scientific anomaly, something relatively rare statistically speaking. But rarity does not necessarily mean that something is disordered. In that case, following the same logic, people with an IQ above 150 are extremely disordered.
Whether something is disorderly is a normative statement, and such questions are not answered by the scientific discourse, even if it may be informed by it.
To make it short: You cannot derive an ought from an is. Science deals exclusively with the 'is' part.
And there isn't some miraculous rainbow sparkling above all the one's dealing with sex and gender, no matter how much you all want to march down the streets with them :wave2:
I expect that the majority of them are far more pleasant than you, considering that you are a proud racist anti-semitic misogynist.
