You’re right that sex phenotypes (features other than gametes) and gender form a spectrum and not a strict binary. This is often a point of confusion and I’ve had people try to argue about sex, after I’ve explicitly differentiated between sex and gender.
I think the cartoon is likely about sex, but if everyone agrees that sex != gender and biologists define sex as binary in humans, then it doesn’t really matter and we all agree about the important things.

There are only two genders: binary, and non-binary

There are 10 types of people in this world…those who understand binary, and those who don’t.
