Islamofascism is not communism; communism is (nominally) a materialist ideology, while Islamofascists actually dislike Western "opulence" (or at least claim to; methinks there's some jealousy involved). Different breed of cat.
The basic dynamic is same. Instead of powerty, muslim extremists are fighting perceived corruption and immorality. And instead of future socialist paradise, they're fighting for paradise in afterlife. Same cat under different fur pattern.
