CydoniaNights: I guess you’re kinda right about the "it’s biology" part. Biology says males have to work for it and females get to choose the lucky one. But to claim that the slut part isn’t sexist... My god. We live in a society, lol. Calling women sluts because they have lots of sex IS sexist. "biological" and "sexist" aren’t mutually exclusive. Again, like every other specie (or at least most of them), human males work for it and human females get to choose. But I’ve never heard of anyone calling a female seal, tiger, elephant or cat "a slut" because they sleep around. Only humans do this because I guess animals don’t have social issues like sexism and etc.
Hey Julia, sorry for the delayed reply. Life has prevented me from taking the time to respond in a meaningful way, but I have the time now so here goes.
The reason I believe calling a woman a slut is not sexist is because being slutty can apply to men too, and does get used for men (although not as frequently). Although the word itself is not generally directed to men, there are other words that mean the same thing that are tailored to the male gender and carry the same negative connotations as the word slut. Examples of these would be manwhore or gigolo. There are also gender neutral terms such as cumdump which can apply to both men and women.
For me, calling a woman a slut does not have the same properties like say "the N word", which can only apply to black people, because it specifically targets the race of the person and nothing else. You can't use that slur towards other races because in order for the insult to make sense it has to be applied towards a black person. Which is why I consider using the n word with malicious intent a racist slur.
Being deemed a slut is based off a person's choices and character, not their gender. Not every woman can be called a slut and have it make sense. But you can call any black person the n word and it will always make sense because it is a race based insult. You can also call men sluts or slutty and have it make sense.
I also want to look into calling someone "a player" and what it actually means to most people. Yes calling someone a player does have some positive connotation to it. Again it's because biologically, for a man to sleep with lots of woman, it means he's desirable and successful sexually with the opposite sex which means that in a sense being a player is a type of accomplishment. Sadly this just isn't the case for woman. So unfortunately woman can't possess the positive spin of being promiscuous because it requires very little effort to achieve the status unlike men.
Something that people overlook though is that being labeled a player also carries a lot of negative connotations to it as well. Woman don't tend to like promiscuous men. "stay away from that guy, he's a player" is pretty common phrase used by woman. Most parents don't encourage their male children to sleep around and most women don't want to date promiscuous men. Generally both sexes want faithful partners. Marriage was designed specifically to encourage men to stop being players and to look after woman and their offsprings. It's also the main reason prostitution is looked down upon, because it was and still is allowing men to cheat the marriage system and allow men to be slutty with very little consequences. Being a player has never been encouraged throughout history. Sure if your good with women you might get propped up by your friends and admired by men who aren't as successful sexually, but no one is encouraging men to be promiscuous. Society, the law and even religions all want men to avoid sleeping around and have designed laws and practises to do exactly that.
So based off all this I just can't consider it a sexist slur. It is definitely insulting to call someone that unironically, but I wouldn't say it's sexist.
Also your analogy about calling animals sluts just doesn't make sense, because animals don't have the same biology or mating practises that humans do. Most female animals can afford to be slutty because gestation and childcare require much shorter periods of time and have a much smaller burden on the mother's body. Human males play a much more important role in childcare than almost every animal. Some exceptions would be penguins, seahorses, lions and certain primates, who also play a big part in childcare. Also when would it ever come up where you would call a animal a slut? Most people don't call random animals slurs let alone sluts. Slurs are generally reserved for people you don't like, not animals that are just minding their own business. This is probably why you never encountered this scenario.
I hope I properly explained my thought process, regardless of whether or not you agree with me, I hope you can at least understand my perspective. I also want to emphasize that I don't think it is a good thing to call people sluts and is something I avoid calling people. That being said there isn't anything wrong with being slutty in this day in age (woman or man), I don't look at escorts as inferior woman, they just have a different lifestyle. One that I greatly appreciate. Escorts have made my life a lot more enjoyable, have given me confidence, helped me be better in the bedroom, thought me a lot about woman and help me see beauty in things I disliked or was hesitant to try.
