It's more that male/female is not a single binary, it's several bimodal spectra. Chromosomes of xx or xy don't perfectly line up with birth genitals, birth genitals don't perfectly line up with endogenous hormones, and endogenous hormones don't perfectly line up with internal sense of self, several of those things can be changed later, and none of them are clear binaries.

Gametes are not "several bimodal spectra." They are a single binary. And they are what define male/female.

In excess of 99.98% of people have the genitals naively predicted by their chromosomes.

This is one of the closest-to-perfectly-binary phenomena that exists in nature.

Not even 99.98% of people have unambiguous genitalia (it's about 99.5-99.97% [1]), before we even get to people with the "opposite" genitalia of what their chromosomes would suggest. An in any case, genitalia was only one of the 4 things I mentioned, and are also one of the ones that can be changed later.

Frankensteinian surgical mutilation is not really "changing genitals".

[delecti]

Trans bottom surgery has one of the highest satisfaction rates of any surgery. You're entitled to your opinion, but I'll rely on the opinions of people actually living with the surgical results. This [1] lists a 94-100% satisfaction rate, which to me feels a fair bit higher than one might normally expect from victims of "mutilation".
