Timothy McVeigh and the Unabomber are heroes to some.
Cross posting from another thread because it's in my clipboard history, making this easy:
There's a lot of stellar reporting on this stuff. There was a limited-series podcast about the evolution of white supremacy in the US that did an excellent job of explaining and illustrating the shifts called Long Shadow trailer. It starts with Waco and Ruby Ridge and really helped me better understand how and why we're seeing what's happening today. (Scroll down; the white supremacist eps were preceded by a season about 9/11, which I haven't listened to).
The gig-economy metaphor makes more sense with the perspective that they understand that the KKK is unpopular and they rely on small cells and individuals for acts of terror and violence. Then the leaders of the movement can "condemn" the violence, which was what they always wanted and knew their rhetoric would bring.
