Whether Islam is pure evil, and Christianity is superior to it is IRRELEVANT TO WHETHER THE ALLAH VS. JESUS STORY IS TRUE.
Hate to be a broken record but people need to get past simply believing everything that they'd like to be true is true and everything they'd like to be false is false.
It's clear a lot of people are just so thrilled with the story because they WANT it to be true they're missing how unbelievably unrealistic it sounds.
And, for the sake of argument, let's say Islam is pure evil and Christianity is perfect; how is the proliferation of a falsehood in support of Christianity over Islam good? Or does it not matter if this particular story is true or false?
I hate Islam and the false prophet profoundly and would love nothing more than to see it wiped off the face of the earth for what it's doing to the souls of children and civilization.
That said we don't need lies or half truths to expose it for what it is. There is plenty of solid evidence that it's nothing more than an evil political cult of the Ishmaelites.
It COULD be true, depending on time, place and the individuals involved. Clearly, there ARE Muslims who believe it is their duty to kill infidels.
Speaking historically, this is hardly a new phenomenon - lot's of Christians have killed Muslims for exactly the same reason (remember the Crusades ?).
In fact, a lot of Christians have killed fellow Christians because of disputes about whose dogma is best (remember the Spanish Inquisition, or even Northern Ireland today).
Seeking the freedom to believe as they chose, led to the ultimate arrival of my Anabaptist Ancestors in Pennsylvania in 1709 (because some of their relatives had been burned at the stake in 16th Century Switzerland).
The U.S. model for "freedom of religion" is really unique in the world and we are somewhat naive to believe the rest of world thinks as we do.
In the words of Rodney King, "why can't we all just get along?"
