The issue of white extremism is taking on a new and important role in the American political conversation, and it is separate from the problem of guns and the people who will use them to mow down their fellow citizens.
The two issues mix together after mass shootings carried out by racially motivated killers. But they are often distinct.
There was apparently no racial motivation for the gunman in Dayton, Ohio, who carried out his massacre hours after a gunman in El Paso, Texas, posted a racist screed and then shot up a Walmart. And there were no guns involved in the violence surrounding a 2017 gathering of white nationalists in Charlottesville, Virginia.
