The way it works is this. You recruit some excitable young people into neo-Nazi groups. You recruit some more excitable youths into the Antifa. Then you sic them on each other.
While they whoop each other’s asses, they represent no threat to the neoliberal order. Thus, the young population that could potentially question this order is declawed, defanged, and distracted.
In the meantime, the general public is horrified and will that more easily accept one of the pillars of neoliberalism, which is securitization.
