I'm not generally a vengeful sort of person, but injustice absolutely can fester in my psyche. There are honest mistakes, but then there is deliberate abuse for personal gain or even mere pettiness, and the latter sort is infuriating. Self-righteous "Karens" and other people who seem to sincerely believe their behavior is for some "greater good" might be the worst in day-to-day life, though. They bully with a clean conscience as if their own inaction would have been the real injustice.
Yep, I agree with that line about injustice, people preying on the weak and all; it happens so often and I'm not inclined to let it slide if there's something I can do.
And...the Karen's, don't get me started.
It's a complex issue which is why I was fed to raise it, based on my most recent situation, to see what people though. Looking at it generally is one thing, but it really needs to be dissected, something that's difficult to do with a short comment. Interesting how people have responded for sure.
