I’m really impressed by how consistent these posts are, both in terms of content and frequency. Thanks for the good work!
If you’ve ever dragged around the rotting carcass of a grievance like this, you’ll know how unpleasant it is and how little good it does. Over time the harm caused by the original insult can be dwarfed by the harm caused by how rotten you feel every time you return to dwell on it. But in spite of this it can be frustratingly difficult to just drop it and move on.
For personal injustice, like someone being unfair or mean specifically to me, I agree wholeheartedly. Yet couldn’t you make the same argument as for anger in the general injustice case? That “holding grudges” against racist discrimination for example is necessary in some sense to take action against it?
