In the linked essay, I mention Nancy Mace's standard TERF question, asked most recently to Tim Walz: "What is a woman?"
My answer is simple. A woman is not a what. A woman is a who.
I want to expand a bit from the essay on why I think this matters.
Fascists like Mace know we are wired to accept premises, and so they construct questions in such a way as to win the venue. This is true even if we disagree with the person who is offering the proposition. We accept the frame, then we argue the contrary position.
But first we accept the frame.
