What line does this walk? Things that are even physically possible and things that are not? I just can't believe Snopes dedicated cycles to debunking this.
Thankfully it got some press and they changed the label to "satire". I can't tell exactly when because the snopes link has been excluded from the way back machine (for whatever reason).
But a lot just turns on being juxtaposed against a prerequisite belief that's not universal. If you don't share that belief, it won't be funny to you. That doesn't (necessarily) make it bad satire.
Perhaps the publication should look inward, not outward, and realize the lines between misinformation and satire are paper thin. Somehow, and perhaps its branding, The Onion manages to maintain humor and absurdity with very little room for interpreting it's content as anything but satire.
There are plenty of people who don't find the onion, at all. It's not a justification for blacklisting them as fake news.
The Onion is, literally, fake news regardless of whether one finds them funny or not. The question is whether people think it's true not whether they think it's funny and that's the only decision being made by a fact-check.
Forum users posted the article from BB asking for it to be debunked. They haven't posted a request for articles from the Onion and that's likely because the Onion is well-known enough for people to know it's satire.
You guys are reaching so hard here.
