I think the first step to equality is to make an effort to treat both sexes as equal, which means either we make no sexual/gender based insults at women or men, or we make them to both. Personally, I don’t think I’ve ever used the word slut, but I also don’t think it belongs on the same level of taboo as blanket racist or sexist terms like nigger or cunt. To me, the word slut particularly references a degree of sexual immorality or uncleanliness, which is obviously up to interpretation based on the user and the intended target, so I can’t see it as a generic term to be applied to any random woman.
For instance, if one wants to insult a woman in a gender specific way, say she cuts you off in traffic, cunt or bitch will work in any circumstance, but if you call her a slut or whore, it seems incongruous to me. Obviously, the ideal situation would be to let it slide and use no insult, or perhaps use an interjection that doesn’t rely on one’s gender or whatever, like calling her an inconsiderate jerk.
I still think any kind of blanket ban on it makes little sense. If one discovers that one’s partner is cheating, as the vast majority would consider that an immoral sexual act, male or female, I think a word akin to slut or whore is reasonable. I’d like to think I still would refrain in such a situation, but I’d have a hard time condemning a friend, expressing his or her anger over such a situation, for being somehow gender insensitive for using that term. I have, however, pointed out that I think it’s wrong to others, in the process ofinsulting a female boss, with a similar term, that while she was, in fact, being selfish, inconsiderate, and irrational, and I used a more accurate insult.
That all said, I do think there’s still a double standard regarding the sexual morality of men and women, but it seems to have significantly lessened in my generation compared to others. I don’t think any of my friends see women who engage in regular casual sex as any different than men who do, the woman isn’t a slut and the man isn’t a stud, they both just have casual sex. And even when I’ve known people who have cheated or been cheated on, it seems that the anger is more directed at the betrayal, rather than at the sexual act itself.
