That is troubling
My only personal experience with Muslims is meeting some very nice Turkish women in a bar many years ago. They were great and could party with the best of us. In the course of the evening, one of them told me she was Muslim and I asked her how she could be there looking so attractive and partaking of adult beverages. She explained that like any religion they would stray from the path occasionally but it could all be made right later.
That seemed very normal to me. They were Turkish and not Arabs but it does seem to indicate that in some cases they can be very much like us.
If there is truth in this article (some of it is undeniable), I just don't know what to say.
