Banjo: I understand and agree that putting all in the same category is wrong. It's happened with me with my religious faith as well as in my arboriculture career. I'm sure you have unfortunately been lumped into the same category of hackers by those who don't know any better, even though a comparrison of work would be night and day.
I know there is diversity in Islam. This is why I used the terms "fanaticism" and "extremists" to seperate those Muslims who are more radical in their beliefs. I believe those words put them in a different category. There is even a facinating diversity within the extremist ranks - Sunni, Shi'ite, Twelvers, Sufi, etc. There are also much more moderate Muslims within those ranks, except for possibly the Twelvers, that are great citizens of this country and wherever they live.
I apologize if you felt I over-reacted to your Christianity comments. While there have absolutley been many people doing things "in the name of Christianity" that are not Christian whatsoever, some trends and beliefs have a solid basis, even if implemented incorrectly and taken to an extreme. I should probably have taken your comment as actually supporting my point about extremists views.
There are simularities between the three Abrahamic faiths. However, the differences are greater and, IMO, much more interesting. How they each view the nature of God, human nature (who we are and how we are supposed to relate to Him and each other), the human condition (why we're so messed up), and how we are liberated from our condition are completely different when one looks at the details. I've found that most of the simularities are superficial, though sometimes facinating in a historical and sociological context.
As far as your comment about moral rules to control people and lifestyle choices, every society has to have these rules. There are usually much greater and far reaching consequences which those rules are trying to prevent. The immediate results may not be harmful, but may become so as more accept certain vices as virtues. Just like an early co-dominant it's best to treat it early. And as with most of arboriculture, prevention is some of the best maintenance we can do.
The question, and where societies differ, is what is the grounding, or justification, for demanding the adherence to those rules. Is it simply human-based, or are moral rules actually objective in nature? If Islam describes the correct way to view reality, then I'm screwed. If these Iranian Muslims are actually correct, then they should do what they are doing. However, if the basic Christian idea is correct, then I've got a shot. If there is no Supreme Absolute, then the question is meaningless outside of our own subjective world.
