I cringe every time I hear another guy refer to women like this
Female as the adjectival form of woman is normal and ok. As a noun for a human it tells me you’re on one of a few varieties of bullshit
My teacher is female.
My teacher is a female.
The former is adjectival, the latter is an icky noun. That “a” is doing a lot of work lol.
As a noun: “Females are often uncomfortable being called females.” As opposed to “Women are often uncomfortable being called females.”
As an adjective: “The reported rate of sexual violence among female soldiers indicates a serious problem that is being insufficiently dealt with.”
