Biological science doesn’t tell us %#&%^ about genders. It tells us about sexes. Two, neither more not less.
How I rue the day the word “gender” jumped over the fence of the Grammar Corral and started roaming the wide prairies.
I look at it this way: the use of the word gender is a defacto confirmation that they are knowingly playing word games. If it were really about biology, they'd use the word sex. They also wouldn't have to invent new gender words and then use them to bully people.
It takes a reprobate mind to invent a completely wacko alternate universe of lies, and then demand that others play along or else. I mean sheesh,
"Transgender’ Could Be Defined Out of Existence"
It was never real to begin with.
