Dear Ray Gun:
Patriotism is a Very Good Thing. Even so -- as you know -- "An Excessive Patriotism is the last refuge of a scoundrel."
Likewise, the Bible is a Good Book. Even so: "The Devil can quote Scripture." And, as you have so aptly pointed out, there is a lot in the Bible for the Devil to quote.
The Koran is a Good Book. Millions of good people around the world believe in the Koran, follow its teachings, and lead good peaceful lives. Even so, today, we find many Devils throughout the world quoting the Koran, and misleading the naive and the gullible, to achieve their own evil goals.
So, Ray Gun, even though they can all be turned on their heads and used for wicked purposes, still: Patriotism, the Bible, and the Koran are all basically good things. Why? Because they have influenced many more people to lead good lives than bad lives.
Nothing in human life is black or white, Ray Gun. Everything is Gray -- even the Word of God.
