even if they mean “adult human female” (TERF dogwhistle btw), there are ways of defining “female” that necessarily include trans women. the reason people use “biological woman” or whatever is because they refuse to use the term cis, because it “validates gender ideology” or whatever. “biological women” ≠ cis woman, and is, in most cases, a dogwhistle.
yes the phrase “adult human female” is a dogwhistle, the entire TERF movement has literally sloganized it and it’s very common in anti-trans rhetoric, bigoted merch, and public campaigns. i have literally found stickers with that phrase around my city mixed in with other anti-trans messages. be serious.
