Hello again guys, I will try to answer you questions but currently I would do it rather "briefly" because of other time consuming things I am working on at the moment.
DISCLAIMER: All my answers are of my opinion and the knowledge and experiences I accomulated over the course of my life. I have given myself a place to "answer" because I am of the origin of Islam, to extends I would rather not tell you about, But I am very much and by all means, of the traditional Islam in its purist (or most ancient) form.
I would like to see where and how the false Islam develops and sustains itself.
- Starting from the "where", The uniqueness of Islam that it was not like in other Ibrahimic religions and constraints itself to the private practices and moral guides of the individual and a specific set of people; It went to giveout guidelines and "laws" on how to govern a society or a community where the majority are Muslims. There are two problems that rose up from this. The first was being subjective to different interpretation and manipulations by the "executors" of such laws. The second being the clash against other established or emerging systems and laws.
What we calling "false" islam is actually a specific mentality or a way of thinking taking over a certain governed society, Sometimes the society actually is behind it and sometimes it is not. For example and it is VERY obvious, in Iraq, ISIS is governing by blood and bullets. You believe what they believe or you die. It is sustained by fear and it is alluring to join as you will be feared, it gives a sense of being.... important. Also because it is "loosly" based on some traditional Islamic beliefs. A long beard and a short thobe gives a teenager the sense that this guy is actually telling him the truth behind his belief system. He would want to defend his people, he would want to restore the glory to his country.
Take another example, Egypt. Even thought a specific group is considered radical, The majority of Muslims are not condemning their way of thinking. Most of them think they are the brave warriors of Islam. I can tell you for sure that Osama Bin Laden is considered a hero in many many Arab and muslim countries. Believe it or not at a point even I considered him one. In certain aspects I still believe he is and will always be, But no any more or less than Bradley Manning!. But that is going beyond the question, lets take this section to another post
For the second problem, The clashing of societies, Cultures and belief system. We see it everyday in every country with a diversity of religions that includes Islam. I would quote the legendary Ahmed Deedat with the ultimate answer to this problem and add some to it. He said once "Don't live in a country that you don't think it is worth dying for, Just don't live there, don't complain!". I will add to that "and simply if the disagreement of the society you are living with does not invade or interrupt your personal space and religious practices, Leave!". For example, muslims in many countries are not allowed to legally have more than one wife, Yet so little complains, While in the Philippines the moment you declare you are a Muslim it becomes legal for you to do that, Yet everyone complains!.
Finally I would say that there is no sustainability for "false" islam (lets call it severely radical and chaotic) without blood, money and godless people behind it.
Religions, All religions are good. It is the people that are very bad.
I don't know if I diverted from the question, sorry if I did. I have alot of javascript ode in the back of my head to write.
