So if Americans don’t disagree on all that much, and don’t really loathe one another, why did UVA find that nearly half of America believes “it’s time to split the country”? Such surveys are detecting, as public opinion scholar Omer Yair argues, not animosity toward people in the other party, but fear.

And why have Americans come to fear one another? Because pundits on left and right tell us we should. Because pollsters tell us half the country hates us because of how we vote. Americans are starting to believe those who tell us we’re a bitterly divided nation of extremists, and it makes us willing to give up on a United States.

We’re not on the verge of civil war, nor do most of us want secession. But if we keep listening to the shrill voices who profit from our divisions, that may change.
