I have no desire to learn Arabic to read the Koran in the original language. But I've read enough of it in English to know that your SIL speaks the truth.
The Old Testament has passages commanding the Children of Israel to wipe out heathen populations in order to possess the land, but these are incidental to the book. A fair reading of the Koran has them central to the book.
The Children of Israel had stopped doing this at the peak of their political power, the reign of King David, circa 720 BC. A significant element of the Muslims have persisted in doing so until this day.
Don't give me any libtard arguments on moral equivalence until you've actual read the Koran and studied the history as I have!
Sorry re: post #14. Sometimes my fingers move faster than my brain.
