"Women who insist that trans women are not women often object to being called “cis women” under the false assumption that it somehow undermines their femaleness — this is not at all the purpose of this language. The sole purpose of cis terminology is to name the unmarked majority (similar to how one might refer to white women, or heterosexual women, or able-bodied women, etc.). In other words, referring to someone as “cisgender” simply means that they have not had a transgender experience."
