Of members of Islamic State:

It struck me forcefully how technologically connected they are; they follow the news obsessively, but everything they see goes through their own filter. They are totally indoctrinated, clinging to all manner of conspiracy theories, never acknowledging the contradictions.

Everything convinces them that they are on the right path and, specifically, that there is a kind of apocalyptic process under way that will lead to a confrontation between an army of Muslims from all over the world and others, the crusaders, the Romans. They see everything as moving us down that road. Consequently, everything is a blessing from Allah.

And of a former member of the Westboro Baptist Church:

As a member of the Westboro Baptist Church, in Topeka, Kansas, Phelps-Roper believed that AIDS was a curse sent by God. She believed that all manner of other tragedies—war, natural disaster, mass shootings—were warnings from God to a doomed nation, and that it was her duty to spread the news of His righteous judgments.
