John Gruber at Daring Fireball nails it, as usual:
Fox News addicts justify their continuing viewership on the grounds that, more or less, “everyone does it” — that MSNBC, CNN, The New York Times, The Washington Post, the BBC, etc. all blatantly lie to their viewers/readers in the same way Dominion proved that Fox News lies to its viewers. They’re all liars and thieves, every system is rigged, and everyone in a position of power or authority is crooked. It’s a form of nihilism that, I think, explains exactly how Trump got elected and how he still has significant electoral support. If you believe everyone is a corrupt liar, you might as well vote for the corrupt liar who (a) is on your side in the culture wars, and (b) wears his corruption and dishonesty on his shirtsleeve. And might as well keep watching the cable “news” network that’s on your side in the culture wars, proven liars or not.
