You watch this one thing out of curiosity, morbid curiosity, or by accident, and at the slightest poke the goddamned mindless algorithm starts throwing this shit at you.
The algorithm is "weaponized" for who screams the loudest, and I truly believe it started due to myopic incompetence/greed, not political malice. Which doesn't make it any better, as people don't know how to take care of themselves from this bombardment, but the corporations like to pretend that they people can, so they wash their hands for as long as they are able.
Then on top of this, the algorithm has been further weaponized by even more malicious actors who have figured out how to game the system.
That's how toxic meatheads like infowars and joe rogan get a huge bullhorn that reaches millions. "Huh... DMT experiences... sounds interesting", the format is entertaining... and before you know it, you are listening to anti-vax and qanon excrement, your mind starts to normalize the most outlandish things.
