As a man who has known many Trans individuals, their general etiquette has been: address me as I’m dressed. Thus, if the person is in women’s clothing, then ‘she’ is appropriate. This eliminates any guesses we have to make about the bits under their clothing. Your article would suggest we eliminate all gender specific pronouns and addresses, as we don’t want to offend anyone, because what I read here, you do not take into account individuals who consider themselves both (hermaphrodites) or neither (nonsexed). In your word scheme, where would they fall categorically? You cannot say non-men or non-women, because they are both or neither respectively. You have still excluded someone, and this is the root problem with attempting to formulate non-exclusionary language: it will still create exclusions.
