What is it with conservatives and this "there are only two sexes" nonsense... Are they trying to convince us they arent any smarter than a grade schooler or something. Anyone who has had more than an elementary school education knows full well its not that simple...

@freemo biologically there are only 2 sexes, male and female. If people feel like they identify with certain traits not normally associated with their biological gender, they should be free to.
But it is absurd on its face to attempt to redefine what gender is biologically. Conservatives are pushing back against the attempt to redefine natural law.

@StarAStar No you are confusing Gender and sex.. biologically sex is not as simple as male and female and there are a huge range of bio9logical physical variations (XX, XY, XXY, XYY, XXX, etc etc).. what you describe when it comes to how people identify, thats called gender and is a different topic than what we are discussing, which is sex.

@freemo @StarAStar 99.9% of all human beings have one of the two major karyotypes. Everything you mentioned that isn't XX or XY: none of them have ever reproduced. Some of them cause severe defects too such as Downs Syndrome.

If one day, someone with an XXY chromosome pairing reproduces, and their kids reproduce, then maybe humans will get a third karyotype. It still might not be a different biological sex. Some reptiles and amphibians and fish can change their sex during their lives. For some reason, the vast majority of mammals can't (I'm not sure if any of them can actually).

Jellyfish have seven different stages; possibly seven sexes if you want to define it that way. Human beings, and pretty much all mammals, have two. We don't know why most animals evolve 1 or 2 and rarely 3 or more, but that's the way it is on Earth.

@djsumdog

The 99.9% figure is wholly false. Though you would be correct if you said that true intersex in the middle of the spectrum is rare.

As for if they can reproduce or not, I wont argue that many can not... so what? A person doesnt cease having a sex when/if they become infertile. That really doesnt mean jack.
