You can't call a woman an asshole. The connotation is not quite right.
Even as terms like bitch and cunt are gender specific, terms such as asshole and dickhead are as well, just gender specific towards men. Yet nobody's called sexist for calling Bush an asshole.
I already have worked cocksucker out of my foul mouthed repetoire, because as much as I liked the term, and thought it applied really well to some people, I had to accept that its connotation is pretty much homophobic.
Look, my view is that many things in life are in fact gender specific, and adhering to this is not necessarily sexist. Its not sexist using proper pronouns, for example. And there has to be some levels between proper use of he/she and saying all women should be barefoot and pregnant.
