Hold grudges against companies but usually forgive or forget people.

Very rare for me to hold a grudge. Someone really has to do something extremely bad/sleazy/harmful to me, in order for me to hold it against them. Even then I'm quite good at letting it not get to me and letting it go, or to make sure its dealt with sooner than later. Holding grudges is much worse than doing what's necessary to be rid of them. It can come with consequences, but that's just life.

something deep inside that can't be explained.

even if i wanted to i can't. its tough.

Yes. Without properly hating the people that deserve it, I'd feel complicit in a mindset that sure, might be beneficial on some level, but denies me, all of us really, the right to be a cunt when it matters the most.

I can for most people. I do hold grudges against certain ideologies though. But there are people I hold grudges against, and for their sake I hope I never run into them

Nope, my memory isn't good enough to remember who I have grudges against.

I could be arguing with you all day on this forum, maybe for weeks in a row. It might be filled with personal insults. We might even send each other letter bombs, and one might blow up and burn a portion of my living room. But I'll clean up. Then the next day completely forget about it, and maybe agree with your posts.
