People are animals and animals can be trained. Dogs can be trained, elephants can be trained, tigers can be trained. This fact is hated, but has been known for thousands of years.
Foreign adversaries, political extremist groups and so on are all clawing away at every facet of society that can contribute to training people to be and do what they want. For all of our information, language and intellect, those strengths are just an open vulnerability if they aren't protected.
You have to train yourself sufficiently on the grounded basics of reality, the truth and the nature so that when adversarial training against you and others strikes you can be wise enough to push back like this. You have to be able to surround yourself with people who disagree and stand your ground, because they're all being pumped with garbage from everywhere and don't know any better.
It is one of Russia, China, Cuba's and even Iran's way of attacking the US at a distance by funding these groups and amplifying the dumbest stuff you can imagine until these minority voices reach majority saturation in some of the information spaces where they can fester. Taking over education, journalism, social media and so on.
If the idea of the open society is going to survive into the next century, we're either going to need AI to ground society if we can prevent AI from becoming too centralized, or we're going to need to rapidly change education to teach people to think even if the reason we haven't been doing so up to this point is that it fragments society too much. If the alternative is a fragmentation that our enemies control, then a new enlightenment may be the better way.

It's the USA eating itself and trying to attack Europe, if anything. It's American fascist billionaires who own, buy, and steer these social networks.
