try this on for size:
get a copy of the Koran.
transcribe a section of its text onto your computer. just a few random paragraphs ought to be sufficient.
realize, since all pronouncements of Mohammed bear the seal of Allah's kiss and all pronouncements from Allah come out of Mohammed's mouth, that for all practical purposes Mohammed and Allah are one and the same. So, delete all iterations and variations of "Mohammed" and "Allah" from the text, replacing them with "the Leader".
With me so far? good.
Now, delete all the repetitive BS space-filler, the formalized nonsense of "peace be unto his name" et omnia generis alia. It holds no denotative value. It is just dross: scrap it.
Now, re-read the redacted text.
Ask yourself: What does this stuff sound most like.
For most of your possible randomly chosen passages, the answer is "the Nurnberg Rally"
Comparisons between Nazism and Islam are absolutely valid, as they are wake-up calls to the facts.
Moreover, the Koran is a beautiful document. Claiming that the Islamofascists are the true bearers of Islam is like claiming that David Koresh or Jim Jones represented true Christianity.
The problem is Islamic civilization's failure to adjust to modernity, which is the product of historical and cultural processes, not its theology as such. If you mis-diagnose a disease, you will not know the appropriate cure. And this war is too important to base strategy on silly stereotypes.
