I'm not one for sensitivity when people are getting their heads cut off for the world to see.
I am one for solutions. It seems that a lot (not necessarily most for you politically correct folks) of the Middle East uses Islam as a vehicle for their rather barbaric laws and culture. It's a huge step back for the modern world in that these views are practiced in ways that essentially wipe out all ideals of basic human freedom. There's a problem and it's not the fault of America that these ideals exists.
These are offenses that are of human nature, however, are punishable by death in many parts of the Arabic world.
It's not Islam itself as much as it's the relationship between the religion and the basic principles practiced by people for thousands of years. There's a deep connection there and, while "blaming Islam" isn't politically correct, it is relevant as well as a considerably important fabric woven into the culture of the ME.
There's obviously other factors such as infrastructure, poverty, and lack of basic direction that we here in America take for granted. We enjoy a system that, no matter how flawed, ends in some semblance of unity through democracy.
So I deleted parts of your post because either: A) not relevant to my response; or B) I agree with them. The latter is mainly with your point regarding Moral Relativism which I categorically affirm.
The last part I bolded because I think it is an important trend in your posts and I am going to flip it on its head, a bit anyways
I think the point I made in my Syria post (if you have not read it please stop reading this and glance at it. Will make the rest more clear.) and will further develop here deals with that paragraph.
First, in the study of Islam and Politics, which I am greatly familiar with, there are three main, broad theories that deal with the explanation of radicalism. The first is, as I feel you and many others agree with, ideational. This, in a Political Science perspective, does not always have to be religious. Although,
generally, in discussions of the Middle East it is focused on religion.
The second is an Institutional explanation. While my studies and research has veered away from this I feel it is important to mention. This type of explanation basically argues that the institutions in the Middle East and Islamic world are what is to blame for radicalization. Shadi Hamid, who is quite the scholar of Islamist groups, wrote a book last year called "Temptations of Power" where he looked at Islamists groups post-Arab Spring in Egypt, Jordan, and Tunisia, His explanation is that when institutions are authoritarian this actually results in less-radical Islamists. Jillian Schwedler, on the other hand, is the original writer of this institutional -> radical argument and crafted what she called the "inclusion-moderation hypothesis", which Hamid is attempting to refute, where she argues that inclusion in political systems for Islamist groups leads them to moderate.
The final is a structural, or a political-economic, explanation. This is where the crux of my research focuses and the basic contention is certain structural factors in the Middle East lead to radicalization. The Syria post from prior is part of my much larger research, but points this direction.
Now, all three of these probably play a role.
So why am I bringing this up? Because your last paragraph implies that we are lucky in America to have a liberal Democracy where we enjoy freedom of speech, etc. That suggests, though, it is not Islam that causes radicalism; but rather, institutions. I believe response will be "I believe both have a role to share." This leads to my broad argument turn:
Let's take a look at the Middle East: Bahrain, Egypt, Iraq, Iran, Lebanon, Jordan, Israel-Palestine, Saudi Arabia, Syria, Qatar, Kuwait, Turkey, UAE, Oman, and Yemen. If I'm correct those are the region's countries but I may have missed a few.
Bahrain, Saudi Arabia, Qatar, and UAE all use religion in their rule as a way to solidify control of the population. The population does not complain, not because they necessarily support these laws, but because everyone but ethnic minorities (and sometimes they are included) gain rent from oil. Thus they don't need to worry about paying for school, healthcare, job, etc. This is
partially the reason why during the 1979 Siege of the Grand Mosque in Mecca, Shi'a supported the government (there is a much more complicated sectarian reason that I don't feel like typing in this post).
Egypt, Syria, Kuwait, and Turkey all to a certain extent have transformed into secular countries. In Egypt and Syria, for awhile, showing radical deference to religion was outlawed, and that is what is happening in Egypt more now.
To be honest, my familiarity with the rest of the countries is limited, but my point, is each country needs to be viewed on a case-by-case basis. When you do, in my opinion, you find many more institutional and structural explanation for radicalism than religious. But, a lot of this is from my perch on an ivory tower. I don't mean to be condescending and truly love debates like these so I am interested in your response.
