Actually, no. You don’t have to be black to be a womanist. It has historic ties to black women and the term was coined by Alice Walker, who is a black woman, but it has been extended to encompass women of color in general, in the face of mainstream white feminism that would often forget about them/us. And I quote - “A black feminist or feminist of color.” (from Alice Walker’s own definition here)
