No Harmful Ideologies of the Sex Binary

Biology professor Jerry Coyne writes:

Ecology Letters, which I thought was a reasonably respectable journal, has now accepted a “viewpoint” article arguing that there is no consensus on biological sex, and that a definition based on gamete size—a consensus if ever there was one—is just viable as “multivariate” definition that incorporates a combination of chromosomes, genetics, and morphology.

They’re wrong and misguided in many ways, ...

But they add that the “rigorous research” they propose be done “also challenges simplistic and harmful ideologies of the sex binary”.

One of the paper's more ridiculous arguments is that female hummingbirds sometimes have bright colors, making them look more like male birds. No, bird colors do not refute sex being binary.
