Obviously if someone is just plain wrong about something they should be corrected and not downvoted for it, but when someone posts misinformation it's nice that it can be downvoted out of sight fast enough that it's gone before many people are exposed to it and before a bunch of people have spent their time posting facts/corrections or providing critical context for the benefit of others.

We'll likely just have to agree to disagree on misinformation being a "pretend" problem, and it's understandable if your perspective means you don't consider the downvote's utility in fighting against misinformation important, but I'm glad for it.
