And isn't the entire internet just a giant indifferent shaming machine now? Like I get the desire to right wrongs and whatnot but it's not like the general consensus around cheating or being a deadbeat is positive.

"side piece" being problematic in itself, there are many who would use this wrongly.

A family who sees someone with a partner they don't approve of, the extremely religious not accepting divorce/remarriage etc

Shame was from the beginning of man kind one of the most powerful tools of the community/ society to hedge in antisocial behaviors.

This being said there first needs to be sentient consensus on what is anti social behavior shared within the affected community... and that's what we're apparently lacking currently. Robbing millions of americans of the means to life peaceful and fullfilling lives and raping kids seems to acceptable to at least a third of the population.

It's a correct take if you have an audience of strangers though. So it's not that bad when it comes from a social media post like this.

Calling out behavior is better at shaping a community than moderation behind closed doors

Exactly. Ethics can differ. Of course you can say something privately if there is a real problem, but this is some 1950s bullshit I don't want to go back to
