Eph 6:12: "For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places."
Let's be cautious about talk of genocide (post 29). Justice is essential, war may be necessary, but let's stop short of blanket genocide, just because people don't worship the same God, or just because a small percentage of fanatics want to trigger Armageddon.
We can, must, and will, handle this without resorting to genocide.
