We used to refer to biological sex as exactly that: sex. And gender only referred to linguistics. Nouns in many languages (and boats and hurricanes and the like in English) were a particular gender; but, animals (and humans) were a particular sex.
G. Gordon Liddy (of all people) had a radio show back in the 90's, and I remember him saying we should not bow to the liberals, who were seeking to replace the word "sex" with "gender" with regard to biology. He thought they had some agenda behind that. I thought he was crazy. Little did I know, he was 100% correct. By conflating biology and linguistics, here we are.
Now, back to my point: If you are a biological male, and I can be fired for calling you a pronoun which correctly indicates you are a biological male, then you are anti-science, or anti-truth, or anti-reality...call it what you will.
