It stems from a tired, failed, simplistic but still powerful political model of a society consisting of one privileged class and a number of oppressed ones. From the privileged class rights must be seized; to the oppressed ones extra rights must be granted, all in the name of a fictive social justice that is nothing more than an excuse to tear a society apart class by class. There is nothing subtle about this - the people undertaking this effort are the knowing enemies of liberty and they know perfectly well what they are doing.
Well said.
This is scary, especially given the Europhila of the left-wing here and the overarching desire to be liked by the European intelligensia.
