Re: What Is Wrong with "slut shaming"?
Shouldn't sexual promiscuity be something we should treat as "shameful"?
Yes, but there's a time and a place to lecture people on morality.
No matter your views on abortion, or premarital or extramarital sexual morality shouldn't sexual promiscuity be something that everyone on every side of the belief spectrum rightfully condemns?
Most people are of the belief that extramarital sex isn't harmful, physically or spiritually, if practiced with certain precautions.
You and I know this belief to be in error, but if somebody wants to believe a particular behaviour is harmless or even beneficial, it takes a great deal of suffering to convince them otherwise. Even then, the human tendency for one witnessing harm is to attribute it to factors that don't impinge on one's moral views. Hence abortion, sexual disease, sexual abuse, relationship dysfunction, broken marriages, fatherless children, etc. are construed to be consequences of irresponsible behaviours (or unavoidable circumstances) rather than the sexual immorality itself.
People can rationalize or reason around almost anything, as I'm sure you know.
What could possibly be wrong about shaming people who engage in such behavior?
Depending on how you do it, and the spirit in which you do it, you can potentially make the problem worse.
As a for-instance: if sex is a kind of coping mechanism for a lack of healthy relationships or low self-esteem, heaping shame on an individual without providing them with an "out" or a healthier alternative will only compound the problems leading to the immoral behaviour.
It also goes without saying that there's a proper time and place to lecture people on sexual morality. Of particular importance is that you care about the person you're admonishing and that they value your advice and judgment. When you admonish them, it should be in the spirit of helping them, encouraging them to amend their behaviour. If you're shaming them to demean them and exalt your own righteousness, then not only are you behaving in an unloving manner towards them, they're going to perceive it and harden themselves to criticism.
Incidentally, as a general rule, tossing a blue sky question about "Why can't we slut shame?" into the middle of a loosely-moderated, politically-charged message board chock full of Westerners circa 2019 isn't
quite the aforementioned "proper time and place".
