1/ How do fringe ideas become mainstream? In 2015, I wrote a book about this subject. A lot has changed, but I still think what I learned can help us answer this question today-TLDR, we need to map the information ecosystem, & both the right *and* the left help fringe ideas grow.
We need to repudiate in the strongest terms the politicians and media figures who — whether for political gain or to boost ratings — have used their platforms to promote and normalize “replacement theory” and other starkly racist, anti-Semitic, and nativist conspiracy theories.
