Their belief system, tarted up with sophisticated jargon, is based on crude and unfalsifiable bigotry. From me in PJ Media:
This thinking sees oppression not as something that individuals do, but as a systemic process, as intricate and efficient and predictable as a Swiss watch. In this view, Person A does not oppress Person B. Rather, “society” is structured in such a way as to make any action by Person A oppressive by definition to Person B. Person B is not oppressed by a man, but by The Man.
This is a very dangerous kind of thinking. One effect is to obliterate the importance of individual characteristics. When you shift the locus of responsibility from individuals to “society,” personal morality no longer matters. If Person A works hard, obeys the law, and treats his fellow man kindly and respectfully, he is still an oppressor because of his place in The System. And if Person B robs and kills someone, he can never really be at fault, since his place in The System compels him to do what he does. Worse, if Person B works hard and obeys the law, he is a collaborator. Virtue becomes criminality; criminality becomes virtue.
