@LaurenOxleyx If you are going to present ‘basic research’, at least do it.

1.7% of the world is not intersex. The vast majority of this figure are unambiguous females - adults, mothers, etc - with high testosterone. Do you think such females are intersex?

@LaurenOxleyx Your use of redheads as a reference value is thus inaccurate. And ironically, some of the biggest clusters of DSDs happen in populations where red hair would be unheard of.....

@LaurenOxleyx People with DSDs are not different sexes, they are males or females who, owing to genetic mutations or environmental insult, don’t follow typical development. They don’t represent a third sex.

@LaurenOxleyx That there are only two sexes is a basic fact not only of the human species but in all species that have evolved anisogametic sexual reproduction (almost all complex life on earth). Indeed, it has been modelled as a mathematical (almost) inevitability.

@LaurenOxleyx That *you* think the best way to get your head around DSDs is to remove those people from a basic category of humanity, well, that’s on you.

@LaurenOxleyx And that *you* think the best way ‘to science’ is to declare fundamental knowledge incorrect because of incredibly rare outlier data is, well, that’s on you too.

@LaurenOxleyx Outlier data that, I may remind you, are predictable from our understanding of how the two human sexes develop (and because biology isn’t perfect) and has actively informed that very understanding.

@LaurenOxleyx So next time someone feeds you a line or a stat, maybe check it’s actually true before you use it to patronisingly beat people over the head for their lack of education and before you weaponise those with clinical developmental issues to further your ideology.
