Just wondering -- without having read this thread in any detail -- is there ANY religion (not just Islam) that actually relishes free speech? Think carefully, now. How many do you know that feel comfortable having their undemonstrated assumptions (on which the whole religion is based, after all) challenged? Heavens, I can even remember when Catholics weren't supposed to read the Bible for themselves (the Bible was in Latin, and only priests were taught to read it).
Questions are an essential part of free speech, and every religion I've encountered only countenances questions in the form of "how can I be saved..." as opposed to "how can that be true?..."
I asked questions in Sunday School (we're talking maybe 1955 now when I was 7) that got me kicked out completely. Apparently, I was making it difficult for the other kids to be indoctrinated.
Sorry, but it ain't just Islam. Religion demands faith and obedience, and without both, can't survive.
