There are two genders. If you have a penis, you are a man. If you have a vagina, you are a woman. Anything else is a statistically irrelevant genetic defect.
People come up with all kinds of "identities" but its all nonsense. If you are a dude who has his dick cut off and reformed into a replica of a pussy so you can pretend to be a woman, you are still a man. A very insane and self destructive man, but a man nonetheless.
A huge part of the problem i have with this is that its being pushed on kids in the publik schoolags. This crap is just another facet of the ever encroaching globo-homo cultural marxist agenda and should be pushed back upon.
