Read Exodus and study it. In it you will find the basis of nations built in freedom of individuals; doing away with slavery; and making judgments in light of a higher power (that is, not just depending on our own decisions about what is right and wrong).

The United States was, in great measure, founded on principles of "Abrahamic" religion.

And when you speak of the "worst thing to ever happen to mankind," cite me another system under which slavery was abolished. ALL societies had slavery; societies based on Judeo-Christian values were the ones to eliminate it.

Cite me another kind of society where individual freedoms allowed people to escape their heritage and make new lives for themselves. This last point has been described like this: When you look at the level of wealth of the common man, the graph is like a hockey stick. It's a straight line with no improvement until our present Western societies came about. At that point the hockey stick took off, increasing personal wealth incredibly dramatically.

None of this has anything to do with people like the Sheikh, who misuse Islam for... wow, what for, really?
