Also, gender. No, gender is not isomorphic to pronouns. Many languages don't have gender at all, although they might have an intimidating number of pronouns (Japanese again). Or they could mark gender on the verb instead of the pronoun (Hindi). Or many other configurations. The "thing" that is being gendered varies. Sociologists and anthropologists study this. The gender worldview that comes with English doesn't need to be forced on speakers of other languages.
