I think you're all missing the point, its not the book that is evil or even relevant as a use for or against an arguement, but rather for reference.
i agree with this part, and this is important because it means that even though we both understand the book isn't necessarily relevant to an individual's eventual beliefs and actions, it can be used as a moral base and reference.
Christians commonly no longer follow the bible to a T, but muslims commonly do, and the ideas in both vary from good to evil, sonce christians take only or mostly good values, then the book's reference becomes unreliable. But, since muslims follow all of their book's values, good or bad, their book is a reliable reference for predicting their actions and arguements against them.
this, however, is a bold claim. you're asserting that muslims, as a whole, are more inclined to stick to their book's literal text than christians, regardless of how countercultural or questionable they are, and this is a claim i'm skeptical of. what makes a muslim human more likely than a christian human to do this? you would need to provide specific figures that prove this phenomenon
But above all else, their actions must be compared to their source ideology, and if they match a specific pattern, such as lying to a large sector of people to lull them into a false sense of security so they can slowly gain power and slowly clench the iron fist, then action needs to be taken to prevent this.
but however, here, you're saying that individual actions and the base book
are intimately related, and this seems to be in conflict with what you opened up with. the rest of the quote is pure politics and has very little to do with religion, so i don't think it's highly relevant here
regardless though, again, even talking about books isn't very worthwhile. the fundamental issue is that people who are prejudiced have developed their prejudices by absorbing information that confirms their biases and rejecting information that challenges them, by no choice or effort of their own, and no matter how irrational it is, it's a psychological gymnastics to maintain that these patterns do in fact exist in reality, even if they don't.
