people just saying stuff doesn't make it true. That's literally all I've ever seen a fact check do. Claim stuff and then cite others claiming stuff. Fact checks do NOT tell facts and never will. They may have been objective once, but they sure aren't anymore. I know many on the left will treat them as the all-knowing always factual final say on all matters, and then say you don't believe facts if you don't agree with them, but that is all meaningless.
