My comment was also aimed at the original work. The thing is should we write such a book, and what purpose would it serve? How so by just pointing out the obvious? We all know there are some Muslims who do things like illicit relations and lesbianism. They too know that "muslims are not a homogenous bunch of Arabs but come in all sorts." Define 'mainstream culture'. How is it a good thing integrating into it? What are these barriers?
