People hate feeling manipulated, but they love propaganda that feeds their prejudices. People voluntarily turn on Fox News - even in public spaces - and get mad if you turn it off.
Sufficiently effective propaganda produces its own cults. People want a sense of purpose and belonging. Sometimes even at the expense of their own lives, or (more easily) someone else's lives.
To you too: are you talking about other people here, or do you concede the possibility that you're falling for similar things yourself?
I assume you mention fox news because that represents your political bias and that's fine with me. But for the sake of honesty i have to point out that the lunacy of the fringe left is similar to that of MAGA, just smaller maybe. The left outlets spent half of Trumps presidency peddling the Russian collusion hoax and 4 years of Biden gaslighting everyone that he was a great president and not senile, when he was at best mediocre.
