Admittedly, John McCain is one of the Republicans I find myself agreeing with from time to time.
We are secluding ourselves in ideological ghettos. We have our own news sources. We exchange ideas mostly or exclusively with people who agree with us, and troll those who don’t. Increasingly, we have our own facts to reinforce our convictions and any empirical evidence that disputes them is branded as ‘fake.’ That’s a social trend that is going to be very hard to turn around.
