The second feature is oppositional (rather than complementary) and mutually exclusive (rather than inclusive) value dualisms, which place greater value (status, prestige) on one disjunct over the other. In canonical Western philosophy, the dualisms of male versus female and culture versus nature have historically done this; they have ascribed greater value to that which is identified with males or culture than to that which is identified with females or nature.  According to these value dualisms, it is better to be male or culture-identified than to be female or nature-identified.
