 So very, very different experiences, but if I had to distill it down to one common thread, I think for me it came down to every single person I have met with throughout my career who has been involved in an extremist movement. And by the way, this is not just about domestic terrorism, neo-Nazis, far-right groups, but it's also about Salafi jihadism and other forms of extremism. The commonality is a desire to be a part of something that is greater than oneself, and the desire to feel like you belong to something that is greater than oneself.
