Gender is genetically more complicated than 8th grade biology. Beyond the different chromosome pairings, there are different epigenetic manifestations from genes that exist on chromosomes that aren't on the 23rd pair (i.e., the "sex chromosomes"). Some of these are pretty well understood, like the XY folks with Swyer syndrome who develop a uterus, fallopian tubes, vagina, etc.) and other aspects aren't yet fully understood, like XY folks who develop a penis but psychologically flourish with super low levels of testosterone (which in cis-gender men is generally psychologically debilitating).
If you have a Y chromosome you’re male.
Males should not be permitted to compete in the female category.
Progress is being made. Lia Thomas was not permitted to compete in last year’s Olympics.
This is a classic losing issue for Dems.
