Antifa are the useful idiots of our era. Rile up a bunch of young people with extremist ideologies. Goad the most stupid and impressionable ones that are of little to to society anyway into comitting crimes and terroristic activity, then use them as justification to ramp up surveillance and central authority as the common folk welcome in the increased lack of privacy and expansion and further militarization of civilian police forces, then charge the antifa types and incarcerate them when they cease to serve a political purpose and become problematic.
