Why haven't women fought back?
Women who have tried to fight back have always done it as individuals, making it much easier for them to be dismissed or targeted themselves as money-grubbers or attention-seekers. ["]We["] have not fought back because many of us have been ashamed, believing that somehow the harassment or assault was our fault...

A pragmatic explanation exposes competition among females (and women) to criticism of "feminist" leadership, capital, and political satisfaction many individuals would rather ignore.

"The two features considered in hypotheses 3 and 4, male control of resources and male potential for polygyny, have important implications for female reproductive strategies. This brings us to the fifth hypothesis for the evolution of patriarchy.

"Hypothesis 5. In pursuing their material and reproductive interests, women often engage in behaviors that promote male resource control and male control over female sexuality. Thus, women as well as men contribute to the perpetuation of patriarchy.

"As Hrdy (1981) pointed out, it is not always in a female's reproductive interests to ally with other females against males. Often, females do better by competing with other females and/or allying with males. Among humans, such female strategies can reinforce patriarchy."
