If one delves deeply into patriarchal psychology — a dangerous, and thankless task in all — one finds that it is the role of patriarchy, and of patriarchal types, wherever they can be found, to teach women and Negroes how to speak properly.
A woman, as we ought to know, is unspeakable. As Eve led Adam to conclude, her very body parts will lead to the downfall of Man. This sense of things is the psychological factor that leads right wingers to always attack the way she is speaking. The point is to reduce her to shame, to let her to reflect upon the unspeakability of her body parts — and to reflect (above all) on how these led to the downfall of Adam.
Blacks, as we also know (via Ian Smith and the Colonial Experience) fail to speak properly. Whether it is the devil in them, or just the lack of English in their original culture, the failure is palpable in the eyes of those whose English makes them rational enough to govern others.
Nowadays Negroes see themselves as better than women — those whose unruly body parts appear to make them impossible to govern. Yet both Negroes and women remain unable to speak. That is because they still need to learn all the techniques that are entirely necessary for them to speak properly.
