It's objectively the truth that sex is another class category created by humans to sort people and enforce a hierarchy of sex.
This is patently false. It was a category to distinguish between two observable variations of human. The category of man/woman existed in the annals of history far beyond what we know today. Before we were humans, we knew instinctively what a man/woman was. You see these systems in herding species already. Don't give me this "we created this division just so we could dunk on others" bullcrap.
