In explaining exactly why this is so bleak, Klippenstein references the dystopian science fiction movie Minority Report, where people are arrested not for anything they’ve done but for “pre-crime” predicted by people with psychic powers. In this real-world case, the “indicia” (indicators) of future political violence listed in the report are:

anti-Americanism,
anti-capitalism,
anti-Christianity,
support for the overthrow of the United States Government,
extremism on migration,
extremism on race,
extremism on gender
hostility towards those who hold traditional American views on family,
hostility towards those who hold traditional American views on religion, and
hostility towards those who hold traditional American views on morality.
