Last time I checked the US was probably 83-90% Christian...etc...of those Christians probably 65% are armed...with the remainder taking up arms if there ever were to be some type of violent armed incursion by islmofacists in the US...so...honestly, I dont give the Jihadis a snowballs chance in the Sun's corona of totally destroying the US.
Onward Christian Soldiers...
The Islamic invasion is already in progress. It is more subtle than hordes screaming across the border swinging scimitars. Every time a California schoolchild speaks the conversion formula in a mandated class to "study" the different culture, there is a small Mohammedan victory. Every time A news anchor refuses to identify the religion or ethnicity of a perpetrator of a crime who is Mohammedan there is a victory. When a city is intimidated into allowing the muezzin's call 5 times a day out of loudspeakers on the mosques there is a victory. Refusal to profile Moslems boarding airplanes is a victory, etc. And watch the Mexican border and those who have crossed. When Islam has its foothold in the US I expect the Latino illegals and their now legal derivatives to begin to convert because that is how they will gain real power in America. Once it starts it will go quickly and suddenly we have perhaps 20 million of them. The Mohammedan "chaplains" are already converting fanatics wholesale in our prisons.
