Then you popped into with a completely different reason. I'm still working on the original argument. We came up with more than two words to express the concept.
Rayiner's response: "It can’t be that complex if virtually every human society came up with two distinct words to express the concepts."
"Two distinct words" plainly refers to the two sexes. Virtually every human society ("most of us") hit upon classifying humans into these two categories, with very rare exceptions that I'm sure you're itching to point out right now. You have tried to perform a sleigh-of-hand "gotcha" by pointing out that there are many words for women and many words for men, but you're barking up the wrong tree if you think you can gaslight a dog like me into believing that is a rebuttal of Rayiner's point.
It’s only complicated if you start from the premise that language must accord the same importance to the experience of small minorities as to the experience of the overwhelming majority.
