"Third, just as in classical economic Marxism certain groups, i.e. workers and peasants, are a priori good, and other groups, i.e., the bourgeoisie and capital owners, are evil. In the cultural Marxism of Political Correctness certain groups are good – feminist women, (only feminist women, non-feminist women are deemed not to exist) blacks, Hispanics, homosexuals. These groups are determined to be “victims,” and therefore automatically good regardless of what any of them do. Similarly, white males are determined automatically to be evil, thereby becoming the equivalent of the bourgeoisie in economic Marxism."
