Perhaps since we seem to have widely adopted 'kid' for children we should adopt 'nanny' and 'billy' to avoid gender terms which appear to make women a subset of men. I also quite like the various spellings of women that take the men out of it (wimmin, wymyn, &c.) Perhaps we should also lobby for changes at other levels; homo sapian (thinking man) should be replaced with the more evolutionary accurate and none gender specific anthropoid sapian (thinking ape).

There are also times when changing the language is not the answer to changing attitudes and more fundamental changes have to occur or we get the silly situation where words just develop two opposing meanings (as in 'health care' which is, of course, concerned with illness)
