Over the past 40 years, all that has changed. The long tail of the internet coupled with the evolution of our politics has divided us as never before. Even COVID, an outside enemy that should have united us, has become a cultural and political cudgel. Ironically our collective anger over politics may now be the only thing we have in common, even as it’s devolved into trench warfare.

We are divided into superclusters of like-minded people. People so siloed that they are literally shocked that everyone does not think and vote as they do. In short, reality has become negotiable and we sort ourselves accordingly.

The weaponized culture wars lead to more enmity, disgust, and dehumanization of our opponents. One wonders if all the king’s horse and all the king’s men can ever put the Humpty Dumpty that is our political civility back together again. That's the reality that Peter T. Coleman looks at in The Way Out: How to Overcome Toxic Polarization.
