I remember the gulf war, I remember long established members of the boards I inhabited at the time, usually but not always with a right-wing lean, going absolutely bananas at the time. And even the more reasonable ones basically lost the plot. If you really want a conspiracy theory, I'd point to the government and Fox news being desperate to pivot from 9/11 to one of the wars they'd been planning.
I also remember Reddit during the last election. Political sub-reddits that only had Bernie fans and internet libertarians during non-election years suddenly got swamped by "normal" people, and the regulars started conspiracy theories about who all these people were with their "weird" opinions.
The fact is, reddit's demographics skew young & educated, any outside observer would expect them to be more liberal than the average American, and they mostly are, even accounting for the male skew and the pockets of reactionaries that make their home there.
The whole Correct the Record thing is on a par with pizzagate. I'm always saddened that I can't tell the difference between those who've been naively sucked in and those who repeat these things out of a political motive. I used to assume they were mostly in-the-know, but my faith in humanity has ebbed and I can no longer attribute to malice what is adequately explained by them mostly being brainwashed by the most feeble of conspiracy theories.
