KAROL MARKOWICZ: Blood Libels: Conservatives don’t get to mourn after national tragedies because they’re always forced to beat back the idea they caused it. “After every horrible mass shooting, when we should be mourning together, looking for solutions to stop future attacks, consoling the families of the victims, there’s an immediate rush to make sure conservatives know they do not belong to that wider American community feeling the pain. Worse, there’s a constant allusion to the fact that those on the right are responsible for the slaughter. Republicans spend the time following these attacks not in mourning like they should be but beating back the sickening idea that they inspired the shooter.”
