I remember my dad telling me about when he discussed the role of women in Islam in a college psychology class. Apparently, unlike the West, where women are typically seen as being the purer and more innocent of the two sexes, the opposite is true in their culture. Women are viewed as sinful, corrupting and scandalous, while men are wise and pure.
It's not like the Qu'ran (spelling?) says "Women are evil", it's just something buried in their subconcious and culture. It's really no wonder they hate the West so much considering how cruel and backwards their culture is(in our eyes, at least).
Still, punishing the VICTIM of a rape is absolutely wrong, no matter how messed up your worldview is.
