"Twitter is 90% someone imagining a guy, tricking themselves into believing that guy exists and then getting mad about it"
I think you could substitute "Twitter" with just "social media"
This is standard journalistic practice - one person is happenstance, two people is coincidence, three people is a trend.
Point being, it is not just the systemic political issue of being for or against that SA suggests shores up the Weak Man, but their beliefs themselves which shift and flow and pop in and out of existence. The only antidote to not fall in with the politics or the belief is to maintaina sense of self doubt and empathy. (And i say that as someone who also self diagnosed with much research, but also doubts).
And even that doesn't protect you from other peoples' beliefs. Has no one read Foucault's Pendulum?
Sadly Dan Brown didn't.
But no. That book has an undeserved reputation for being difficult.
