Someone's taking a crack at it--in Turkey. An official Islamic body is attempting to delete some of the more offensive of the hadiths. Rather surprisingly, there's been only minimal grumbling and no protests. It has the the full backing of the Turkish government, too--which is currently dominated by an openly Islamic (and rather conservative) party.
Oh, and because I can't resist OTOH, consider this Freedom House report on Saudi hate literature found in American mosques [scroll down for the link].
Something to keep in mind as my humble suburb gets its first mosque, due to open in 2007.
Oh, and Bernard Lewis, a respected authority on Islam and the Arab world, has taken notice of significance of August 22.
