I don't even really see the individual posting these threats as the root of the problem. Every generation of people is going to have some people who are capable of learning to love doing the most heinous shit imaginable, especially if they're convinced that doing so will make them a heroic defender of "their" people. What turns 'ordinary men' into monsters is group dynamics and authority pushing them towards the conclusion that violence, even to people who are objectively not guilty of anything wrong, is the only answer.

So-called commentators and intellectuals on television and the Internet, who are never going to endorse blowing up a school or conducting a mass shooting, but will bang on day and night about children being in danger and that the "groomers" and "predators" need to be "stopped", I blame them far more than any one paranoid lone wolf with a gun.

People like this need to be shot out of the atmosphere.

Basically shot in the back of the head. Execution style.
