Actually, God created two sexes.
Man created genders, first as a linguistic construct vaguely associated with the sexes, then as a euphemism for the sexes, then as a way to deny the facts of biology inherent in the sexes in the interest of social engineering.
I asked the question: What is the difference between sex and gender?
From Medical News Today: The words sex and gender are commonly used interchangeably, but many linguists would argue that their usage is quite distinct. Sex refers to the biological and physiological characteristics, while gender refers to behaviors, roles, expectations, and activities in society.
I've always used them interchangeably, but then I am NOT a linguist. Nor am I a social engineer. I DO get your point. Thank you.
