Barton Swaim:

Why American politics in the 21st century is marred by incivility and mistrust is the subject of more books and essays than any normal person would wish to read. The premise underlying most of them is that it’s a left-right problem: The right hates the left and the left hates the right, only the reasons for the hatred vary according to the author.

But what if it isn’t a left-right problem at all? What if the acrimony and loathing that animate our politics have more to do with class than ideology, more to do with educational status than any set of views on culture and policy?

The assumption that the nastiness of our politics is chiefly a matter of warring ideologies wouldn’t explain, for one thing, the mindless rage currently evident on elite campuses. These are places dominated by a confederation of left-progressive worldviews, yet the acrimony issuing from them is ferocious: occupations of quads and academic buildings, chanting mobs in the grip of antisemitic lunacy, assaults on Jewish students, flag-burning exhibitionism, dizzying varieties of “intersectional” preoccupations glomming onto the cause of anti-Zionism, and on and on.
