I don't understand why so few people know this.
GENDER is not the same as SE.X.

Why these pathetic labels exist in the first place, I seriously don't know.
Gender is what you mentally are, and often decides what pronouns you are called. "He" for male, "Her" for female, and "Xem/Zem" for those who identify as gender neutral.
Se.x is what you biologically are, decided by chromosomes.
Mental vs. Biological.
Shouldn't be too hard to remember.

To answer any questions, yes, I am an FTM transgender.
