Sometimes when I'm watching the Internet news unfolding, I feel like I'm in one of those weird dreams where everything looks the same, but all reason is inverted in some way that only the people in the dream understand. The Internet brings down barriers, including those comforting barriers that provide a cozy space for our moral certainty to flourish. We lapse into approaching problems from the circle of our own experience, sometimes not noticing that we have traveled into very different places. And we mistake our viewpoint for our values, aligning ourselves with others who share a common attitude or rhetorical framework.
