The last half dozen or so American traitors that were caught passing info to foreign countries, im talking FBI and CIA and US military, I dont recall ANY of them being muslim...
This is just as stupid and near sighted as looking at German or Japanese Americans (Or German Canadians, thats my side of the family), as something less than trustworthy in WW2. Stupid. There is not a shred of evidence that muslims are any more prone to ending up as spies or as any other ethnic or religious group.
Learn from history or repeat it. Btw muslim fundamentalism is only ONE threat the US and the west faces right now, its not the only one. You could think up a rationale for distrusting almost any group of people if you set your (small) mind to it.
Look at Tim Macvey...quite the hero he turned out be be huh?
