What's actually happening is that what were previously localized parochialisms, individual or groupings of extremists who were isolated from one another, have become interconnected in a globalized way and have thus become, or are becoming, mainstream.
实际发生的是 先前被局限于偏狭地方的 个体极端主义者或是集体极端主义者 他们曾被互相孤立 但现在以一种全球化的方式互相联系了起来 因为成为了，或即将成为，主流。
