I limit myself on social media these days, especially Facebook, because I’ve noticed this very thing. I’ve watched it with my friends and family on both the Left and the Right. Everyone comfortable in their own echo chambers, reinforcing their own biases. Every where you turn, there’s a meme, a talking head, an outraged conspiracy perfectly placed and nobody questions why, or where it came from. And because it reinforces their own views, nobody wants to. In fact, they fight very hard to defend it, instead.
