'Cis' is ideological language, signifying belief in the unfalsifiable concept of gender identity. You have a perfect right to believe in unprovable essences that may or may not match the sexed body, but the rest of us have a right to disagree, and to refuse to adopt your jargon.

J.K. Rowling It’s so strange that outside of the ‘West’ no one is talking about cis, he/she, they/them, it/bit.

Dr. Ruwayda Mustafah Very strange, isn't it?

J.K. Rowling Dr. Ruwayda Mustafah Surely you're aware of gender fluidity and third genders in non western cultures? How do you reconcile that with your resistance to their emerging validation in western culture?

Harpo J.K. Rowling Dr. Ruwayda Mustafah Yeah that’s bs so no reconciliation required.
