First off, I don't have a problem with Islam or Muslims in general. I don't care too much about the religon itself one way or another. IMO, it's simply a vehicle for immature, repressed people to lash out at anyone they percieve to be responsible for their oppression. A great many of them buy their government's lies about the US, aka the Great Satan. I have a VERY big problem with those governments that use religon as a tool to manipulate the populace to keep them in line and their anger directed at someone other than themselves. It's also an easy out for people who are angry about their situation and feel unable to do anything to challenge the system that oppresses them. They would prefer to lash out at another target they see as weaker, or at least unwilling to punish them for their views. There is also a perverse pleasure in being the underdog, which a lot of these people see themselves as being.
I think it has very little to do with Islam. I believe in God and Jesus Christ...they don't. I don't consider that to be morally inferior, just ignorant. Like many other religons, Islam has been interpreted differently by different people. (Witness Shia, Shiite, and Sunni Muslims, for example) My problem is with the ones who interpret it in a way that is dangerous, foolish and belligerent for no other reason than to promote their view of the Western world as degenerate and as a basis to attack us. I am not, nor have I ever been, one of those "My God is better than your God people". I personally don't care if someone wants to worship a ream of paper, so long as they don't use it as an excuse to attack me. Their worship of paper isn't the problem, it's their belief that everyone must worship paper or die. Not everyone that follows Islam believes non-believers must die, any more than every Christian believes every verse in the Bible is meant the way they are acted upon by someone else.
The fact that very few Muslims besides the jihadi's have the guts to speak out doesn't automatically mean they agree...it just means they aren't brave enough to call these people what they are, or to stand up for what THEY believe Islam to be. They are a cowed people, imo.
Your analysis lists possible explanations but assumes that they are susceptible to change by pretending they are morally or ethically equals in faith and in deed appears to be an exercise in futility, since it has zero effect on where they live and what they experience and hear daily.
This is absolute gibberish. I can't address it directly, because it makes no sense.
It also means that they have no THEOLOGY on which to criticize because it is fundamentally OK in the Koran to kill.
