Although the entire world knows which human beings are “women” and not “men,” if feminists cannot agree on this matter then it is not clear how feminism can advocate for the well-being of women. Third World, poor, and racially marginalized women need the support of First World women, who in turn might learn from the practical forms of organizations developed in less advantaged countries and cultures. Without a perceived commonality among women, there is no basis on which common political ends, such as health care, education, child care for working mothers, and preservation and care of the natural environment, can be collectively pursued by feminists.
