Can a man be a feminist? If so, what would it mean? I want to participate in a dialogue between women and men on how to accommodate women's moral concerns. I propose that the fundamental values of justice embodied in the South African constitutional democracy require men to be feminist. These values provide the best safeguard of the important interests and values of both women and men. Men who accept these values can support the main concerns of feminism. The implications of the argument in this article range from public issues to the most private aspects of marriage.
