"I'm thinking about somebody that has zero friends and how, you know, you're not part of a community then," he says. "And where do you find that? Well, you find that on Twitter by taking a side with this side or that side." He adds: "We get some kind of a common enemy for somebody with no friends to put up a tweet and have a bunch of people like it or retweet it"
