On page 163, Baca Zinn and Eitzen say that the traditional sex roles approach to the family defined the sexes as dichotomous. What this means is that boys are boys and girls are girls and never the twain shall meet. A nondichotomous approach sees crossover between the behaviors and characteristics of men and women. If want a brief refresher on this notion, you could go back to Gender and the Social Construction of Reality in the Glossary Review . The family is a source of struggle over resources, etc.
Men benefit from the combination of capitalism and patriarchy.
For some, this notion of family portrayed in this section is a difficult one to swallow.
