Your own experiences that you have described that these precepts are NOT predictive. You´ve said yourself that the Muslims you know run the gamut from potentially violent fanatics to extremely nice people - how are the core precepts of Islam predictive of that?...
I think you misread there a bit; try again.
Certainly fundamentalist approaches to any line of thinking, even in science (and they occur), are bad. Understanding truth as anything but the provisional interpretive representation of observations, agreed to consensually, is dangerous. (In fact, to go one step more: To declare a one-to-one mapping of that mind-dependent reality to an external reality "out there" happens, in terms of proofs, to be a leap of faith.)
I am keenly aware of Christian fundamentalism in the US, Canada, Australia, and now even the UK and Germany. Given that some of its proponents and financiers have political agendas, it worries me greatly. But I think the fight there is more about transparency in political financing, and the use of unlimited funding for campaigns, and the utter nonsense about corporations being people. I am
not concerned, however, with this as a religious movement as much as I am with the backroom politics that nourish it.
Recall, for example, the financing and tacit support of the Nazi party by the conservative establishment as a way to head off support for leftist or moderate proposals in the Wiemar Republic. It was a horrible idea then, and it is being repeated on a much larger scale now, on both sides of the Atlantic. Look out!
I am coming just now from an econ & public policy forum where these issues are addressed. I have opted to discuss the philosophical side here on JREF, however. I think it is the appropriate place.
And once again, given the death totals and potential for more, my greatest concern at this juncture in history, in religious terms, is understanding Islam.
I know there are effective and knowledgeable posters who are Muslims, or who were raised so, posting here on JREF, and am hoping that, in correcting any of my statements, one or more of them might provide insights ~ based on fact ~ that are helpful in gaining more nuance in my positions. I most definitely do not fear being proved factually incorrect; it is a path to better knowledge.
To be explicit: I am reeling a bit from what I understand, provisionally, about the differences in the books written in Mecca and those in Medina, which change tone quite drastically (Sura 9 is often quoted in this context).
And I have had the personal experience of a peaceful neighbor going Islamic fundie on me and launching quite a revealing exposé of feeling, along with threats. (This is not the only context for such experiences, as I was nearly shot by a close friend during a coup, based solely on my nationality.) I like to try to get at the root of these things, since they happen to me and others around the world. In the second case, I have needed to delve into historical Catholic fascism, as fascinating as it is disgusting.
Yes, there are Buddhists going nuts in Myanmar, but in this case, I find nothing in the core teachings* to support it, and so understand this as a social and political problem, not one indicating any sort of source in Buddhist canon for these behaviors.
*I could be wrong on that last, and am willing to stand corrected. I am not thoroughly familiar with Buddhism, and am making an assessment more on its public portrayals in my own culture; admittedly sloppy on my part.
