There are two meanings to the "f" word: one is discussing sexual intercourse, and the other conveys contempt for a person or a thing. The first meaning is given when you tell someone, "I want to f--- you," and the second meaning is given when you tell someone, "F--- you."
Why are we to understand that a word for sex expresses contempt? You're supposed to have affection for your sexual partners, not contempt. There's an element of self-loathing involved in it, basically saying, "If you would take me as a sexual partner you must not be worthy of my esteem."
Why don't we refute the idea that one should have contempt for one's sexual partners? And that would begin by no longer using the "f" word in the second sense. This would seem especially true from a feminist perspective. Feminists who use the "f" word in the second sense are inconsistent, on the one hand supporting female equality but on the other hand continuing the notion of having contempt for the things that we f---.
("But, A Random Stranger, the verb 'to f---' implies no gender!" I disagree; there's a reason that the Blink-182 song "Dammit" includes the line "did you hear he f---ed her" instead of the line "she f---ed him." Most people instinctively feel that the guy is doing the verb.)
Instead of implying that someone having sex with them is the ultimate worst thing that can happen to someone we hate, let's move on to other expressions of contempt that don't have anything to do with sex. My personal favorite is "die in a fire." Very little ambiguity there.
