I think it was Mark Twain who said: “If you call a dog’s tail a leg, how many legs does a dog have? Four: calling a tail a leg doesn’t make it one”
What we appear to have now are not two sexes, not four! We have:
1) male (M), defined as having an X and a Y chromosome;
2) female (F), defined as having 2 X chromosomes;
3) fauxmale(FM), defined as having 2 X chromosomes with a male sexual orientation, and may have surgical modifications (e.g., breast reductions); and
4) fauxfemale (FF), defined as having an X and a Y chromosome, with a female orientation, and may have surgical modifications (e.g., breast augmentations).
If a FF claims to “really be F”, just remind them that every cell of their body has an X and Y chromosome, that they do not have ovaries or a uterus.
This clears up many problems (e.g., and FF cannot compete in F sports). No discrimination against sex or sexual orientations.
Give them what they want - their own sex! Problem solved.
We are neither God nor Nature.
They are mammals.
Mammals have one of two sexes.
File a complaint with God, Nature, Darwin or the Flying Spaghetti Monster if you don't like it.
But reality does not change.
