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.
