Discontinuity

From the Seattle Times:
BAGHDAD — The U.S. military suspended a Marine on Thursday for distributing coins quoting the Gospel to Sunni Muslims, an incident that has enraged Iraqis who view it as the latest example of American disrespect for Islam.
The Marine, stationed in the western city of Fallujah, handed out silver-colored coins this week that said in Arabic: "Where will you spend eternity? (John 3:36)." The other side read: "For God so loved the world that he gave his only begotten son, that whoever believes in him shall not perish but have eternal life (John 3:16)."
"We are sorry for this behavior," said Mike Isho, a U.S. military spokesman in Anbar province, which includes Fallujah. He said the Marine, whom he did not identify, distributed only a few of the coins and that the episode was under investigation.
"This incident doesn't represent the morals of the Marines," he said.

Does this not make sense to anyone else? If the Muslims insist that the Bible is one of their Holy Books, that it's teachings are to be respected - then I fail to see how receiving a coin with a question and a quotation from one of their holy books can be offensive. If the question and the chosen quotation prompts further thought - then doesn't that mean that more study should be spent in all of the holy texts to determine the answer? If Islam is the true religion - then further examination of its texts and the encouragement to question and delve - should not be taken as a threat - but rather a welcome opportunity.

For example - this last fall, Jehovah's Witnesses began calling our house and I had extra time, and thought - why not practice Russian? The conversations were fascinating and I started reading the Bible in a new way - everything I read wasn't just the same old same old - but attested to Christ as the Son of God and equal to him. Most excitingly, due to a the question of who can accept worship and the JW referring to a passage in the Old Testament where Joshua falls down in worship before the Angel of the Lord - I learned about Theophanies and Christophanies - something I had never known of before and which has enriched my reading of the Old Testament and my understanding of the continuity of God's plan.

If Muslims are truly convinced of the the truth of Islam, if they truly believe the NT to be a Holy Book - Then why the discontinuity?
