Legions of critics endlessly cite the logical flaws and dangers of "Identity Politics" on the left and even on the right, but as Mary Eberstadt points out, they overlook that emotionally, it's deeply authentic and heartfelt. Indeed, it has become the key to its believers' personal identities.
Now, in some ways, politics has always been about identity, but it's been based on identities that people could take for granted and don't have to prove and constantly have affirmed: first, family; then place, religion, and ethnicity. And Americans have always formed like-minded, politically-active voluntary groups, including ones based on minority race and ethnicity.
But looking for the causes of the surging rage and occasional mass hysteria that now swirls around I.P., Eberstadt notes that the normal sources of "identity" throughout history, especially family, have lost most of their power and permanence. We have far fewer people whom we consider "family" in the sense of loyalty, commonality, permanence, and identity. And you don't have to share Eberstadt's traditional Catholic views of sexual and family issues to be concerned about the breakdown of families and what rough beasts are emerging to replace them.
