Gender doesn't equal sex. And sex isn't a binary either. [Redacted this bit for misinformation that I was too tired to catch. Beat me up for it, do it. If you want context feel free to scroll through the rest of the thread]
Ari Berkowitz Ph.D. - "For a variety of biological reasons, many of us have external gen****s that are intermediate between a c******s and a p***s and intermediate between l*bia and a scrotum. Others have typically male chromosomes but typically female gen****s. Still others have intermediate gonads, called ovotestes. Collectively, all these situations can be described by the umbrella term, inters*x."
PhD Candidate Darren Incorvaia - "It’s certainly true that there are two types of human s*x cell, sperm and egg, produced by testes and ovaries respectively. But the issue at hand isn’t whether gametes occur in a binary; it’s whether s*x does. And in humans, it is possible for an individual to possess both ovaries and testes, and to produce both types of s*x cells (or neither). Historically these individuals have been called “true hermaphrodites,” and today they’re generally classified under the broader umbrella term of inters*x. If we’re classifying humans into male or female s*x categories on the basis of possessing certain gametes, two categories isn’t enough. S*x isn’t binary.
Okay that was way too easy. Maybe you’re thinking, “Well what about chromosomes? There are only two types of s*x chromosome arrangements: XX or XY! If we define sex using chromosomes, isn’t it binary?” And the answer is: no. XX and XY are not the only s*x chromosome arrangements humans can have: there’s also X, XXX, XXXX, XXXXX, XXY, XXXY, XXXXY, XXYY, or XYY If we’re defining s*x on the basis of s*x chromosome arrangements, two categories isn’t enough. S*x isn’t binary.
BUT WAIT, maybe you’re thinking or saying aloud like a weirdo. “Isn’t Y the male chromosome and X the female chromosome? Isn’t that a binary?” And oh, my poor misguided imaginary friend, the answer is again no. Obviously the most common “male” s*x chromosome arrangement is XY, which means X isn’t uniquely a “female chromosome.” But there’s also the added fact that possessing a Y chromosome doesn’t always mean an individual develops traits we traditionally consider male, like testes and a p***s. The gene that primarily controls development of these traits (or genes that control this gene), sry, can sometimes be non-functional or jump off the chromosome entirely (this is an oversimplification of course but you get the gist). In these cases the individual usually develops traditionally “female” traits, like ovaries and a v*gina, or some combination of male and female traits. S*x isn’t binary."
