Neither Gender Nor Anatomy Are Binary

Gender Isn't Binary, And Neither Is Anatomy by Archie Bongiovanni and Sarah Mirk   explores the science behind the misunderstanding of gender and anatomy that underlies so much of our contemporary culture and politics.
"About 1 in 1,000 people have a different configuration of internal and external parts. They're intersex."
Frequently they are surgically altered while babies (and unable to give consent) to conform their anatomy more closely to our binary notions, not for medically necessary reasons. Typically, they are lied to thereafter.
 This is stuff I didn't know but makes sense when you think about the science and politics. It will be interesting to see if our next generation does better.
This is another great graphic explainer by The Nib.
