You are saying "80 million people is nothing". I disagree, I think 80 million people is a lot of people.
And the field where that prominence matters, astrophysics, refers to anything that isn't hydrogen or helium as a "metal". Definitions are fluid. Insisting that everyone tediously say "people who may possibly become pregnant" rather than the simple "women" (with the more precise existentially quantified, more and less inclusive intent being clear from context) is itself extremely intolerant.
and thus, unasked by intersex people and without a clear theory of how this would help, you would destroy the concept of sex-based-rights which keep four billion people and the world's children safe?
