Why would anyone need a guide to use a completely mundane term like "biological sex"?

I got curious and looked it up

The phrase biological sex is common in scientific writing as a synonym for birth sex, natal sex, or assigned sex at birth. Outside of medical literature, assigned sex at birth is preferable over biological sex if used in this way.

But biological sex in particular is a more politicized term than birth sex, natal sex, or assigned sex at birth. Colloquially, many critics of trans inclusion use biological sex instead of assigned sex at birth to falsely imply that a person’s “real” sex is unchangeable, can only be male or female, is only reflected by their anatomy as assessed at birth, or is always readily apparent.

Sounds a lot like "Our opposing movement likes to use this term so you should use the terms associated with our movement instead"
