Because the war protestors are just as evil as the scum they are in overdrive trying to protect. Disregard their naivete and ignorance, for those are merely disguises they wear to pretend they're not evil. It is way past the point that anyone can possibly claim they aren't aware of the monstrous evil of Saddam and his regime. They have seen the truth, and they don't care. These are people who would form a human chain around Satan himself to protect him from God.
They have, in fact, been doing exactly that for years.
