Zero dispute. I’m challenging the notion that Americans are rising to that call. (Or cheering on specific attacks, versus general notions of violence.)
In a weird way, maybe social media helps in this one instance. We can’t let the enemy be faceless. There is no glory in shooting a specific mother or nurse.
This is a problem. But it’s categorically different from vigilantism. That sort of grassroots violence is basically impossible to stop once it gets started without major abrogations of rights, at least temporarily. And we have not seen organized grassroots vigilantes taking up arms to pot Trump’s enemies. Not systematically or at any scale that doesn’t just scream gun-control problems.
You're attempting to find step 1 when we're already passed that and into step 2. The vigilantes are coming from inside the house, and the murders committed in Minneapolis combined with the government working overtime to shield them should be the primary signal.
