Any biology class I took always mentioned the outliers of XXY, XYY, and XXYY.
For the vast majority of people, you have only two sex chromosomes, either XX or XY.
So who really feels uncomfortable knowing this? It’s this new phenomenon that is now called transgenders and non-binary.
I’ve only met one true hermaphrodite in my life. She was a woman in every usual way, but had a lot of facial hair, which she struggled to hide; the bearded lady if you will. Nice person, very humble. Not anything like these attention whores that have become so abundant these days.
.....For the vast majority of people, you have only two sex chromosomes, either XX or XY......
And the vast majority of people who identify (or who are identified by their parents, etc.) as transgender or nonbinary are either XX or XY! In these cases, “transgender” or “nonbinary” are mental illnesses!
I went to graduate school on an NSF Graduate Fellowship. This worthy program still exists. The new NSF “trans” program is bogus in the extreme, and should cease to exist!
