Identity liberalism, as I understand it, is expressive rather than persuasive.

I would say that the one incredible thing that Karachi has going for it is the unabated supply of new migrants that pour into it day after day. It could be a poor factory worker who simply wants a job, it could be an ambitious guy coming for an education - they all add hope and vibrancy to the city. Now, this is not something that is generally taken as positive in Karachi. But the hope is that the migration that comes into the city replenishes its stores of resilience and energy.

Toward the end of the campaign, we interviewed some voters in Raleigh, N.C., which is a generally Democratic city, and I'm thinking of a young couple. They had two kids. They described themselves as Christian. They oppose gay marriage. And they were saying that even though they didn't like Donald Trump, they were thinking of voting for him. And one of the reasons was they felt that they were - their very views were making them socially unacceptable. They were feeling a little alienated from the world.

The Republican critique here is that Russia is in a weak situation, but has been emboldened by a weak response from the United States, that in Ukraine, that in other places, the United States has not stepped forward.

Karachi captures all of those rifts between ancient and modern, communal and individual. You see them playing out in people's lives.

[Identity liberalism] says, on the one hand, you can never understand me because you are not exactly the kind of person I've defined myself to be. And on the other hand, you must recognize me and feel for me. Well, if you're so different that I'm not able to get into your head and I'm not able to experience or sympathize with what you experience, why should I care?

President-elect [Donald] Trump has made a provocative choice for secretary of education. Betsy DeVos comes from a wealthy Michigan family. She is an advocate for school choice. That phrase means, in essence, directing public education money to charter schools, private schools or parochial schools.
