I sometimes wonder how the rest of the world copes with these ideas - specifically the non-English-speaking world.

For instance, the occasional language does not have gender-specific pronouns. Are they immune? Many languages have gender-specific definite and indefinite articles. Many also have gender-specific words for many types of pronouns:

Personal pronoun:  he, they, we
Demonstrative pronouns: this, that, these
Interrogative pronouns: which, who, whose
Indefinite pronouns: none, several, any
Possessive pronouns: his, yours, ours
Reciprocal pronouns: each other, one another
Relative pronouns: which, who, that
Reflexive pronouns: itself, himself, ourselves
Intensive pronouns: itself, himself, ourselves

Are comprehensive lists provided where those languages are in use?
