Slut shaming

Slut shaming is not calling someone a slut for wearing revealing clothing or posting a picture with cleavage. Sure in a sense, yes it is, because they are probably using the word slut in a negative way, but slut shaming is attaching a negative connotation with a sexually promiscuous woman or a "slut". So saying "wow everyone needs to stop slut shaming you, you're not a slut for wearing that" isn't actually working to end slut shaming but actually is instead working against it. 

Sure I agree there is not a direct (or really any) correlation between clothing and sexual activeness or promiscuity of any certain person , however reassuring someone by saying "don't worry you're not a slut" is in a way, shaming those who are sexually promiscuous by alluding to the fact that being a "slut" is in fact something to be ashamed of and insulted by. 

Sex is personal, often private, and different for every single person. Some choose to have multiple partners and are happy with that and others choose to have one partner and are happy with that. Basically as long as we are all being safe and having healthy and consensual sex, it's not fair to judge one another based on these choices. Either way there is no reason to be ashamed. Being a slut (or a sexually active woman, often with multiple partners) doesn't make you less of a person, dirty, shameful, worthless, etc. as the word often alludes to - so that is why slut shaming should end.
