The existence of sex, as a material fact and its role in reproduction is pretty clear, well known and simple, in the same way as the existence of the heart and how it pushes blood around is not unclear. Sure, shit happens, and congenital mishap occur. Like for me. I wouldn't

have lived if it wasn't for modern open heart surgery. True, the exact functioning of the heart at cellular level...is complex, but its existence and basic role are not disputed. In the same way, sex and reproductive anisogamy have been known as facts for a very long time.

And with this knowledge, the identification of 2 groups of humans: male &female/ Men &women. It is simple. Always was. And the anecdotal occurrence of DSDs, or the complex biochemistry involved in specific aspects of sexual reproduction do not change the (clear) big picture.

Now we have smarty pants, who because they are very smart (cough), think that the complexity of embryogenesis completely invalidates the clear, simple big picture. It is like saying that my congenital heart defect puts into question everything we know about the existence of the

Heart and how it pumps blood around the body, and that anyone who says "all mammals have a blood pump called the heart" is a simpleton because embryogenesis is complicated.
These people are not smart, they are intellectually dishonest sophists driven by a sex-denying agenda.

It's an absolute evidence to anyone that there are female and male ppl, with 2 different body types, different reproductive potentials and who are raised differently under our cultural systems, leading to different levels of entitlement, vulnerability, social status, aggression..

Telling us that this assessment (biological sex exists, is binary and men and women are 2 distinct populations) is false because of rare congenital accidents or rare psychological conditions

is like telling us that the heart doesn't play a role in the vascular system because I am alive despite a non functional heart and some other ppl believe it is their stomach that pumps the blood around the body.

In other words it is bullshit @EricRoyalLybeck . There is no more nuanced (or rather useful, as it is what really matters here) definition of sex or woman than what we already have, and sophistry won't change that. https://theelectricagora.com/2020/06/02/on-sex-and-gender-identity-perspectives-from-biology-neuroscience-and-philosophy/amp/?__twitter_impression=true
