MAGA dudes never fails to show their ignorance on the most basic of factual matters, like female fertility, like when they can "menstruate". No surprise there, though.
As you demand that only someone that menstruate may use a a "girls bathroom" I wonder when you'll tell your mother she should use the men's bathroom only. This is a trick question too, but hopefully your mother gives you the hard smacking you deserve when you tell her that.
You really are dumb, just like the other bigot Mikado. At least he can say it's due to old age, so what's your excuse?
