I have seen a story on muslims in London. They all are former atheists who were into drinking, deugs and homosexuality who claim they are turninf against all that and former life, supposedly disgusted by British society. they target gay clubs and things of that nature for recruitment.
I am not sure if the leaders like Choubari are closet communists recruiting liberals in a disciplined Alinsky army or if it is the decadence and depression of western leftists like Obama which orient them toward Islam for seeking a meaning to their lives. In any case, antiAmericanism is to a fever pitch.
Muslims are potent evangelists. They fill in the gap left by Christianity wimping out and walking away from the lost.
