Well, Islam does lay down a proper code of behavior, which is primarily intended to safeguard the modesty, dignity and honor of men and women. I guess at this point I should start ducking for cover

Christianity once did, but hasn't done that since the 50s. That's when the value system started changing on a country-wide level. The new modernism with Christians compromising chastity and moral values of Christ with the new freedoms and values of society at large.
I don't think it's Muslim women per se, but the old fashioned morality that was once pretty much the norm worldwide. Let's not forget, we were all created in the image of God, and while we have lost that because of sin, there is still that natural God breathed law and morality in every soul. It's "this" morality that causes Muslim women who have not tasted on the fruit of the west (so to speak) to understand the goodness of moral women. And that's what Christian women have lost when it started choosing the way of the world (of freedom) instead of the way of the Bible (of a bondservant to Christ).
Let's face it, not just Muslims, but all women were more moral (I'm speaking generally) than they are today. Yes, men also. Because there is no light of the Church shinning in the world to brighten man's darkened soul. Christians are too busy being offended to see the immorality in the world, much less the Church.
