how do I explain butler's gender performativity to a biologist?

i've entered a discussion with a biologist about butler's theory, and he keeps saying that butler "denies biology". he *does* seem to understand the difference between sex and gender, but is having a hard time understanding the idea that "sex is already gender from the start". any ideas?

Butler doesn’t say there is no such thing as biological sex, just that gender ends up producing significant constructed notions about biological sex and what a biological sex entails. Just reaffirm that the existence of sex is not without its own major presuppositions, projected onto it by the performativty of gender.
