It's so simple.
1) Male
2) Female
3) Male to Female
4) Female to Male
5) Gender Neutral/Non-binary/Gender Fluid
6) Hermaphrodite
You are either a man, a woman, a man transitioning into a woman, a woman transitioning into a man, someone who doesn't care what gender they are, or both genders at the same time, but there will always be 2 options, until Hermaphrodite becomes available, then there will be 3 options, I imagine some people can have their genitals removed completely.
I don't care if anyone agrees or disagrees.
I'm not attacking anyone.
I'm just stating my opinion.
Take it or leave it.
