If gender is culturally constructed, why "man" and "woman", and only "man" and "woman", are present in every culture? Because, unlike other genders, which are only cultural constructs, "man" and "woman" are also natural features, scientifically verifiable, i.e. objective.

@angelobottone Man and woman arent the only choices in other cultures... Most cultures have three genders, masculine, feminine, and neuter. Keep in mind gender does not mean the same thing as sex of course.

At least 13 languages around the world have more than 3 genders

Several languages have gender systems that dont relate to sex at all as well, for example animate vs inanimate or common vs neuter type languages.

@freemo I wasn't talking about grammatical genders but about gender identity in human beings. I didn't say that "man" and "woman" are the only choices. I said that only "man" and "woman" are universal, while all other possibilities are culturally determined as they exist in some cultures but not in others.

@angelobottone gender identity and gramatical gender arent seperate things. Gramatical gender is the use of terms like "he, she, they" which are ways of describing someones gender identity. If a person dresses and presents as masculine then by definition then masculine grammar is what we use.

@freemo In Italian, the polite way to address a man is using feminine pronouns. In any case, as I said, I wasn't talking about language, but about gender identity.
