Evidence tied to last week's deadly attack on a California mosque illustrates a violent ideology and playbook that is all too familiar to counterterrorism and extremism experts. A 75-page typewritten document, attributed to the teenage suspects, and a livestreamed video showing the attack show extensive grounding in far-right, neo-Nazi thinking. But one facet of the ideology behind this attack has, so far, been left out of much mainstream coverage. "He just flat out says he hates women and that they're the devil and they're destroying everything. And this is an important thing, because that kind of misogyny did not exist in white supremacist circles, say, 10, 15 years ago," said Heidi Beirich, co-founder of the Global Project Against Hate and Extremism.
