Hi Chaimfan,
Regarding why women in Biblical times were more rightwing and righteous than they are today, I thought I'd thrown my two cents in, being that I'm a woman.
In those days, women's main role was marrying and raising children, while their husbands worked outside the home. Now, thanks to feminism, women have had it drilled into their heads that they don't need a man to be happy, that they are wasting their brains, education, and their potential by being full time mothers, and finally, in Gloria Steinem's words, "a woman needs a man like a fish needs a bicycle.
Then there are women who follow this line of thinking who are divorced with children. Since they usually get custody of the children, and they are working full time, they tend to be the most vocal in pushing for government day care, mandatory maternity leave regardless of whether or not the employer can afford it, and finally abortions. Remember, one of feminism main mantras is that women should be able to fornicate without consequences just like men, which is why they are pro abortion.
So in a nutshell, more married women with children are right leaning/right wing, as opposed to their single counterparts, who want the government to act as their husbands/nannies.
