I have a hard time imagining
we'll ever learn how to live together in peace by playing the "whose fundamentalists are most whacko" game.
The moderate Islam take on the Suras and Hadiths which are most unsavory to the west (such as the anti-Jew ones and the ones about the size of the rod to strike your wife with) is to note the historical and cultural context (deeply sexist, tribal, honor-and-revenge based society.) And then to point out the ways in which Mohammad was radical at his time:
treating his wives with respect, advocating for good hygiene, etc.
Which is basically the classic fundamentalist vs. modern-moderate split: do you take these passed down traditions literally, or contextually? If Muhammad based his dental care around a particular kind of locally-sourced twig (which happens to be particularly stellar for oral hygiene), should observant Muslims only clean their teeth with twigs from the same tree? Or, given that he was using the best technology available, should they, ~1400 years later, explore the best of modern toothpaste and floss?
The shellfish and pork stuff in the Old Testament always truck me as an interesting example of the way in which religion and the culture of the time are inextricable. In a society of subsistence farmers, you want your meat to come from animal stocks whose feed competes as little with yours as possible -- i.e., don't raise anything with a cloven hoof for food. If you want to avoid explaining how to safely prepare crustaceans for human consumption, limit your seafood intake to things with scales.
I think it's kind of mindblowing and awesome that one of the best ways to lower birthrates is to educate the women in question: it's win-win. Similarly, I think one of the best counters to radical Islam is to raise literacy rates and supply Qur'ans. We here on the Cellar, none of us scholars of Islam or even fluent in Arabic, as far as I know, have significantly more access to the Qur'an, and with a much wider range of interpretive biases to choose from, than your average Afghani villager whose take on Islam and the world is filtered through a select few individuals.
