William S Lind was one of the first military historians to write about fourth-generation Warfare which is what we are now seeing on the streets of America.
"Marxism takes certain Christian virtues, such as concern for the poor, carries them to extremes and then turns them back on traditional society as weapons. Until there is no poverty, no misery, no unhappiness even, the fight for “social justice” must go on. Since perfection is impossible, the assault must continue forever. In cultural Marxism, these attacks fall under the label “critical theory”.
One outgrowth of “critical theory” is that there can be no higher moral category than “victim”."
