Oh, and one more point: I really cannot believe that anyone still actually reads Ms magazine. I mean, in this day and age...
Beastie is going to have a hard road to hoe in demonstrating why, up until the middle sixties and beyond, rates of violent crime, including rape, were far lower than they are today, while society in general was much more male oriented than it is today as far as family life and gender roles.
I don't think patriarchy is the cause as such crimes weren't nearly as prevalent in the first five or six decades of the twentieth century. If you want the real causal factors involved in the present multidecadal rash of increasing violence against woman, including date rape and spousal abuse, you'd be well advised to talk to Hugh Hefner, not GBH.
It has been the objectification of woman and the trivialization and desacralization of human sexuality that forms the root system that holds up the present tree of increased male animosity towards the feminine.
The rates of rape were lower in the past because more women did not report rape. They did not report rape because they knew the legal system allowed their character to be questioned and their sexual past to be explored in open court.
Honestly, I would have expected even you to realize this, but I guess that was foolish of me. But you may be of the Charity mindset, which is if that the woman doesn't want to call it rape, then it isn't rape. How lovely it must be to live in these repressive patriarchal societies where women are never raped!!!
Your theory is powerless to explain why extremely conservative states like Utah and Idaho have higher rates of rape than bastions of liberal sexuality, like California. The one aberration in this pattern of conservative states having higher rates of rape than liberal states is Washington.
