Then the LORD said to Joshua, "Do not be afraid; do not be discouraged. Take the whole army with you, and go up and attack Ai. For I have delivered into your hands the king of Ai, his people, his city and his land. 2 You shall do to Ai and its king as you did to Jericho and its king [kill every single one of them, man, woman, and child], except that you may carry off their plunder and livestock for yourselves. Set an ambush behind the city."You really need to reason a bit more carefully.
First of all, throwing Christianity and Judism into this argument is a red herring and an attempt to derail the discussion.
The issue at hand is the fact that based on their religious belief, all Muslims are unfit to be American soldiers.
Reason: The central tenet of Islam is Jihad - Holy War - There are at least 164 verses in the Koran commanding the believer to wage war against all non-believers.

Therefore, MUSLIM AMERICAN SOLDIER is an oxymoron.
