Hell, even the president regularly calls for and promotes violence, so I don't think it's that much of a minority. The US was founded on it, after all.
Most of it. Across the political spectrum.

That’s precisely the point. There is a massive difference between doing or aiding and abetting such behavior, cheering it on, and giving into the impulse of “couldn’t have happened to a worse person” before self correcting. There are a few saints who reject the violence at first glance. But most people are in that self correcting phase, and the correction happens the more they learn about the specifics of the assault.

To what numerical end?
How many people live in Iran, who he just threatened to genocide? How many people hold views that Trump thinks make them his enemy, including being critical of ICE? How many immigrants are in the country? It's going to be a very large number, no matter how you slice it.
But some examples: Jan 6, the attack on Paul Pelosi, every ICE agent.
Personally, I've also received multiple death threats from his supporters.
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.
