If you refer to me as she, then you pronoun people are funny 🤣 The difference between "progressive" activists and normal people is that we know who we are and we don't need to convince neither ourselves nor others ;D

It's based on the phenotype.

Yes, as to the phenotypic sex (recorded sex of an individual at birth), I describe it in the article as bimodal, not binary. Soon a paper will come out in Fishes where we could not sex all the individuals for that matter.

Into rare cases they reproduce. According to your what is the sex of an individual, they are female since they have female sex characteristics.

So how does sperm and egg is not binary? Sexual reproduction happens between these two cells and that's what biologists mean by biological sex, which is binary at the very basic level experienced by the tree of life under anisogamy.

According to your logic then almost nothing is binary, but you are mixing the concepts. Before you could not understand the binary of being part of a species or not. Having two types of gametes is binary, however when it comes to phenotypes it's not so simple, that's what I mean in my article...

Having no gametes is not a third type of gamete, therefore no sex can take place, however it obviously creates a third category, sperm, eggs and nothing. E.g., you can choose between two restaurants, go to both or don't go. Not going to a restaurant is not a third restaurant, but it's an option...

Not really, but yes, there are obviously also some differences between straight and gay women.

Legally it's true that it's more about the phenotype. Legally it functions on the observed assignment. But even then, what is important, is that women's issues and trans issues are separately unique, therefore they should not be just pushed together - for the sake of both.. The book addresses that.

True, but in the book there are clear distinctions. I decided not to touch upon gender too much as the definitions there are less established and gender itself as not related to biology.

There are endless basically, but in the paper I cite Sex and gender book edited by Sullivan and Todd (2023).
