The opposite of equality is quality.
That said, insofar as women are humans and humans have rights, it seems more that we should be sure not to be saying we're removing women's rights while still holding fast to some idea of men's rights. Men and women perhaps have separate duties, but duties and rights are not the same thing, and duty is always a matter of context, be that family, clan, company, society, or greater humanity. Rights, to the extent they make sense, transcend such contexts. Duty arises by contract; rights arise from birth.
