- There are two and only two genders.
- Okay, then there are two and only two biological genders.
- Gender is determined solely by biology.
- Okay, it’s mostly determined by biology, right?
- Please tell me it’s determined by DNA.
- Gender can be reliably determined through visual means. After all, no man would ever wear a burka.
- Once gender is set, it never changes.
- Even if the gender can change, it will only change from the one value to the other value.
- Only one gender can be “active” at the same time.
- We’re tracking gender now, so we’ve always tracked it.
- I only need to be concerned with human gender.

Even though this is about assumptions that programmers should not make, and not about "politics", it's no surprise that quite a few parochial reactionaries made it about their political ideology rather than about facts. (And these folks like to talk about "biology" and what's "objective" while making it clear that they know nearly nothing about biology or the scientifically objective mode of thinking that puts data first. Really these bigots are a bunch of emo snowflakes.)
