Andrea Dworkin claims that title, and she has lobbied actively to ban SM, pornography, and most male-female erotic activity you have ever imagined, let alone enjoyed. I've heard Pat Califia referred to as a feminist, but both Macho Sluts and Doc and Fluff include female tops, female bottoms, male tops, and male bottoms, variously dominant and submissive, all playing with one another and many switching roles and partners in remarkable and often unexpected combinations. In one perhaps apocryphal story I have heard attributed to both Pat and Cynthia, the woman in question was dressed in a high-necked white lace Victorian gown while in top mode for a party. I think the same position is useful for SM feminists.
Feminists do anything they want to do in their sex lives.
The key is that they want to. I think both the feminist and masculinist versions of this question proceed from the notion that being submissive means you have no power. When I top I certainly want to get something back from my bottom for my effort. So I don't mean by all this answer that someone's fantasy to be a useless worm trod upon by some contemptuous bitch or brute should not be valued as highly as any other, nor that such a scene cannot be hot. However, it is an oversimplification to talk about the erotic exchange as though it only flowed one way.
