Historical grievances are (unfortunately) nearly universal. They can lead to lasting conflict, much of it involving war and genocide. What makes it all much worse is the practically irresistible temptation for politicians to fan the flames. Grudges are hard to leave behind. Widespread U.S. identity politics is only the latest version.
Obama supporters had hoped for a "post-racial" administration but quite the opposite happened. Here is a panel discussing whether PC elected Trump. This morning's WSJ includes an editorial about protests at George Mason. Are Trump supporters sending thank-yous to the protesters?
Here is the story of a race-predicting algorithm used by the Obama administration to identify bias in auto-lending by looking at surnames and addresses. Systematic bias is a problem to be addressed. But base the allegations on such algorithms? Slippery slopes? Is no one embarrassed? Scared? I am wary of allusions to Nazis but the problem of identifying Jews was (still is) resolved by looking for "Jewish-sounding" names.
Political crusades can lead to awful outcomes. Once upon a time, James Madison and friends saw the threat and wisely concluded that less government meant less politics. And that this was the only way to go.

I am greatly enjoying Jonah Goldberg's Suicide of the West: How the Rebirth of Tribalism, Populism, Nationalism, and Identity Politics is Destroying American Democracy. We are moving backwards, back to tribalism, via our identity politics. The author reminds us of all we are giving up.
