I've had lots of comments get downvoted because other people are wrong and I'm right (not always, sometimes it's the other way around) or because Lemmy insists an issue is black and white when there is nuance. Why should I delete when they're the ones that suck?

Internet points are meaningless and they're forgotten about in a week anyway. Hell, unlike Reddit, they don't even get tallied on your account; they are entirely per post, so even if I were trying to impress anyone, there's no lasting effect of a downvote. It's edifying when the zeitgeist agrees with me, but when they don't, that doesn't change the reason I was moved to comment in the first place.
