A division of people into two (or more) groups. There is some conflict to
what the divisions are, but luckily we have
great minds like AOC to tell us how we
should be divided. Her critical gender theory: those that menstruate, and those that don't.
AOC: My new critical gender theory: there are two types of people; those that menstruate, and those that do not. Some trans women menstruate. Some non-binary people menstruate. Some cis- women don't menstruate.
A rational thinker:
menstruation is "the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina." If you don't have a uterus, you might experience some of the symptoms of PMS, the rise and fall of hormones, with cramping, swelling, nausea, etc... but those are symptoms related to, but is not menstruation.
AOC: You're a man, I wouldn't expect you to understand what menstruation is.
A
critical thinker: It appears I understand the science
better than you do.
