Cote - it is still an odd comparison. Again, what harm does not drinking do?
Also, the Bible is a very different text to the Quran.
The Quran is generally very simple indeed. 1 God, don't worship anyone else, heaven and hell exists, prayer, fasting and giving to charity are good. I would argue that the parts about not scoffing pork, drink, interest and gambling are fairly clear too. Also, do not kill your daughters and you are allowed divorce.
All the above are pretty indisputable, there is never going to be a pantheist interpretation of the Quran, is there?
However, then we come to the parts of the Quran and hadith (I know you have hadith issues, but we'll go past that for now) which deal with the wider social/societal laws.
In Islam, there is naql - the text and aql - reasoning - which is needed to implement the rulings. This has lead to there being an awful lot of leeway and a wide variety of opinions, with regards to many issues, more then people might realise.

The arguments she uses are firmly based in Islamic texts and Islamic history, yet she comes to a very different conclusion then certain others have.
