Yesterday on Twitter, Jason Calacanis had an interesting (if arguably inflammatory) explanation for this: "Looking for explanations of bizarre behavior online (#RachelDolezal, trolls, gamergate, SJW)? two #s: 4.1% & 58.7%. I don't look for explanations of bizarre behavior any more... there are many sick people out there & they are drawn to social media." Where 4.7% is the prevalence of severe mental illness and 58.7% is the percentage that is in treatment. And to be fair, the behavior of the most vocal online extremists overlaps to a large degree with that of people with Cluster B personality disorders.
