I don't believe it, but I do a lot of that internet "world within a world" thoroughly confusing - I'm not interested in pursuing active participation in it ...but would be good to understand how information gets manipulated and promoted.
It's scary. There are "troll" accounts created in advance with pictures of real people (and probably deep fakes now from sites like this person does not exist). They post random crap like knitting or cooking or whatever. They get some followers by posting sharable memes and content. Then they post a random "can't believe Obama did this", then go back to their regular content. They might start out posting things that are true and easily verifiable and lose some liberal followers, but they start posting things that are objectively false and their conservative followers believed the first stuff so why would they question the new stuff.
They're still posting regular knitting content, but they throw out more and more memes for people to share on Facebook and they show people who don't usually share photos how easy it is to share their political memes, and just put a single "fact" out there like oh man I wouldn't usually believe this but I heard that 5g towers are killing bees and thats scary. Then a little while later they say its not just the bees its causing other problems. Oh maybe it's causing covid. And next thing you know, people are burning down 5g towers because they're spreading covid. What. The. ####.
Or they imply that there's some kind of big conspiracy, which is catnip for their followers, but they don't say what it is. Then they suggest that the conspiracy is related to high level democrats, but no details. Then they slowly post "facts" about children being abused, about possible locations where its happening, about possible ways that it might be organized, some link between a democrat and some thing they've already planted seeds about (but no direct connection), and let people draw their own conclusions.
Imagine if i told you your kid was a liar and you shouldn't feed him. You'd tell me to go pound sand.
Now imagine if I mentioned how cookies have crumbs, and that there were cookies in the top shelf of the kitchen cabinet. I'm still sharing funny memes or talking about football or weight loss or whatever. But then a little later, I mention that there were crumbs found near your cabinet.. the one where the cookies were. No accusation, just telling you something and letting you draw your own conclusions. Oh and that there was a chair found near the kitchen cabinet. And wasn't there a kid in the house who had figured out how to reach the upper shelves using a chair to climb up? And that there was a kid who didn't want dinner tonight but now he wants chicken? Would you really do any research on this? Or just trust me because each fact seemed so innocuous?
And then when that kid asked for some chicken fingers would you tell him no, even though you never saw him eat any cookies? And there was already a char in the kitchen, and there were already crumbs on the counter? There's just enough verifiable info for you to believe that this hungry kid has already had a cookie and refuse to feed your own kid.
