Do not believe everything you see on the internet.
Especially so called 'news' on social media.
If a non-negligible subset of Facebook users already believe questionable articles from non-reputable sites, imagine how much worse it'll be when it's a seemingly real video of a politician saying something.
I wonder if it would be effective to produce "vaccination" videos containing polar opposite juxtapositions.
That would be funny. An arms race of cancel-out fakes.
