Iraqis claim Marines are pushing Christianity in Fallujah

[Stranger in a strange land]

Certainly not behavior that should be allowed for on-duty soldiers (and it isn't, the article confirms that much) but I don't see this as a terrible travesty or anything. As long as nobody is being forced to embrace Christianity it's no big deal even if it's inappropriate.

the way it's depicted in the article is extremely damaging to the mission: Iraqis will resent the US presence in the region even more if they feel American troops are trying to push Christinity on them.
