"[R]ight-wing sites and clickbait dominate the platform that dominates American news consumption. And that same platform... keeps making it harder for people to find serious journalism. [...] It’s hard to overstate... how much [this] differs from the conventional wisdom that Americans are just becoming 'polarized' into left and right. The polarization... is not between left and right—it’s between real news and conservative propaganda."
