Of course there is. People believe something is factual. The purpose of debunking is to tell people that it is not actually factual.
It doesn’t matter how a rumor starts. It can be because someone lied. It can be because something got lost in translation. It can be because people misunderstood. It can be the telephone effect. And, yes, it can be someone telling a joke that someone didn’t get.
No matter what the reason, the false belief needs to be debunked, and that’s what Snopes does. They don’t just fact-check politicians or news agencies. Heck, their original claim to fame was debunking urban legends—those stories that pass by word of mouth.
Snopes has long debunked rumors that started from humorous articles. They’ve debunked stuff from the Onion several times, even. They do so by pointing out that this story started on the Onion, which is a satire site.
Satire or jokes are very often how rumors, urban legends, and Facebook fake stories start. Often they even lose a lot of what made them so obviously satire. But, even if they didn’t, all that matters is that some people believe it.
The Babylon Bee is mocking Snopes for doing its job. It makes me wonder if they sometimes create satire because they want some people to fall for it. Though, more likely, it’s virtue signaling to their base, repeating the “Snopes bad” mantra.
