I have heard often, and I pretty much agree, that the majority of Muslims are not terrorists and they do not hold with the radical teachings of their faith.
I also believe, and this belief is becoming stronger each day, that the only solution to the problems of Islam must come from within.
That majority, some 98% it is said, MUST force the changes to have the radical teachings they do not follow removed from the tenants of their faith. They MUST actively work to stop and destroy the radical elements that infest their religion.
With Muslim populations growing, that 2% is significant and is growing.
There is no way Muslims can be accepted into "Infidel" populations without introducing that 2% of terrorists to the host population.
