It's a political hot potato. It gets misused to constrain and contain people.

How we talk about biological sex is a battleground of conflicting agendas and experiences.

But Nature offers us a much wider and wilder view than a basic binary - male and female.

In the confusing maze that is sexual reproduction, sex hormones, sex chromosomes, and genitalia.. are there just two biological sexes ... or could biological sex exist on a continuum just as gender does?
