I think all the writeups agreeing that "everybody loves sluts" are from male writers. (Correct me if I'm wrong.) I just finished reading "Slut! Growing Up Female With A Reputation" by Leora Tanenbaum, which points out that women are often much harder on women who have been labeled "slut" than are men, and in high schools the abuse heaped on people who've been given this label (often inaccurately so) would be considered sexual harassment if it occurred in a workplace. The book also cites the movies "Four Weddings and a Funeral" (where Fiona describes Carrie as a slut when Charles first seems interested in her) and "Chasing Amy" (where Holden cannot cope with the idea that his girlfriend Alyssa has a lot of heterosexual experience, though her lesbian experiences didn't bother him) as pretty realistic examples of how people see the person who is a "slut."
