Women are oppressed as a class because they were born female. This is because of women's *reproductive capacity. Feminism is a movement by and for women (females) to *liberate women from patriarchy/male supremacy. If we deny that women exist, we deny patriarchy exists, and we cannot, therefore, fight it. If we deny women exist and are oppressed due to their sex, we can no longer defend women's sex based rights and protections.
