> permanent
Can you give an example of incorrect permanent punishment? Sacco found a job almost immediately. The truck driver may have a more difficult time, but not because this event will follow him, but because the labor market at the moment is shitty. (And to be clear here I'm not saying what happened to him was right or just).
> The problem is that it isn't so cut and dry.
Sure but now we're in a very fuzzy area. We're no longer saying that public shaming is always wrong, but that there are situations where, in your judgement, the scope is misapplied. Those are two very different situations, especially if you're willing to acknowledge that your perception of the severity of some action may indeed be different than the actual effect of that action.
> The narcissism is real, if you're not closing your eyes to it.
I still don't buy this. People not being self aware is narcissism, but not in the way that you seem to be meaning, which is more like that the activism is performative and not genuine.
Not to say that there aren't people who are performative. Lots of social media activism is, but in many ways so is stuff like signing petitions, and that doesn't get a bad rap.
