" This group tended to agree with dark pronouncements, such as “I need chaos around me” and “When I think about our political and social institutions, I cannot help thinking ‘just let them all burn.’ ” Petersen and his colleagues came up with an unforgettable term to describe this group’s psychology: “The need for chaos.”"

My take is that a lack of opportunity / class stratification / societal mobility plays into this. It's essentially the same reason people play the lottery. When you're stuck in a seemingly intractable situation, you need the world to suddenly change around you. Maybe you win Powerball, or maybe you decide to just burn everything down out of desperation. Social media just amplifies those thoughts.
