Truer words

Youssef Ibrahim tells it like it is, writing that Muslims that believe that they are winning a so-called jihad are deluding themselves if they think that killing other Muslims will help.

This is the ultimate argument against the post-modern apologists. If the 'insurgents' are only fighting because of Western aggression, why are they murdering Muslim men, women, and children? Is there any response that the can give without sounding like they're pathetically grasping for straws?
