I've only read the last few pages, but most people tend not to make that much of a distinction. It's just 'Islam' which is 'obviously' the same from the Arab conquests to the 21st C. This view is a strange case as it is both fuelled by anti-Muslim propaganda and the propaganda of some Muslims.
It tends not to relate too closely to actual history, which is pretty much my point.
Mohammed's conduct in the 7th Century wouldn't be so much of a problem if certain people weren't using it as a justification for how they act in the here and now. That position aside, it's counter-intuititive for Muslims to argue that Mohammed was in direct conduct with the supreme source of morality in the Universe for them to then say that he still indulged in immoral acts - and to then excuse his behaviour by comparing it to the 'less moral' societies around him. Putting Islam (or any exclusivist religion) up on a pedestal, then excusing acts committed for its benefit by saying 'ah, but the immoral infidels did it too' is having your cake and eating it.
If you set yourself up as having a higher morality than those around you then in order to be consistent you must hold yourself to that morality - not the morality of those around you.
