Thats like saying good is a puny challenger to evil. Democracys power is broader than force and tyranny. It captures the imagination and energies of the people, believing that they actually can get something done through the system. Dont be afraid.
My point is that Islam is not a government...it is the religion of evil. The only thing that can stand up to "evil" is indeed good. Evil is far to great to be threaten by any government structure no matter how divine in origin.
