I'm male. I'm even XY. Not all males are. Some are XX.
Sorry, "males" with XX chromosomes are
females, but I'm guessing you were out smoking the ganga the day they had that lecture in health class.
Ah, no. They are males (and look like them) but they are XX.
XX male syndrome - Wikipedia
What you thought was a hard and fast rule is - not. Biology is (unlike most) not a simpleton. Next up, XY females, and XXY, XYY, XXXY, XYYY (watch out, they're nuts), and X0, just one X. The is no Y0, they die in the womb.
Oh, I am aware of Kleinfelters, and the even more rare XYY syndrome that also affects males. But both are relatively rare genetic abnormalities.
Since you persist in failing to provide additional information for your claims, here: "
XX male syndrome (also called
de la Chapelle syndrome, for
Albert de la Chapelle, who characterized it in 1972) is a rare sex chromosomal disorder. Usually, it is caused by unequal
crossing over between
X and
Y chromosomes during
meiosis in the father, which results in the X chromosome containing the normally-male
SRY gene. When this X combines with a normal X from the mother during fertilization, the result is an XX male.
This syndrome occurs in approximately four or five in 100,000 individuals, making it less common than Klinefelter syndrome.
The XY male anomoly, also called Swyer Syndrome, results in an infertile individual with all female genetalia except ovaries. It occurs in about one in every 80,000 live births.
So, either we are experiencing a significant increase in some pretty serious genetic mutations, or we need to leave the bathroom, locker room situation alone. In the case of those afflicted with Swyer's, we shouldn't even need to legislate allowing them to use female facilities, since they already present as females. If they want to use the men's room/locker room, just go into a stall, no one will be the wiser.
Any way you want to twist this tail, it's much ado about nothing. Unfortunately, I suspect that the greatest majority of those "afflicted" by transgender delusions have fallen victim to another fad.
