It is a naive sort of feminism that insists that women prove their ability to do all the things that men do. This is a distortion and a travesty. Men have never sought to prove that they can do all the things women do. Why subject women to purely masculine criteria? Women can and ought to be judged by the criteria of femininity, for it is in their femininity that they participate in the human race. And femininity has its limitations. So has masculinity. That is what we've been talking about. To do this is not to do that. To be this is not to be that. To be a woman is not to be a man. To be married is not to be single - which may mean not to have a career. To marry this man is not to marry all the others. A choice is a limitation.
