The pattern always goes one of two ways. If the killer can be tied to any semblance of a right-wing ideology, it’s a Republican problem. If the ideology runs the other way — or worse — touches one of the left’s sacred identity groups, then it’s a gun problem. Never their own movement. Never their own rhetoric. Never their own political tribe.
When the killer looks like someone Democrats already despise, it’s open season. When the killer looks like one of their own, the ideology vanishes, and the weapon is to blame.
