Anyway, the practical upshot of my English upbringing is that I know a bit about Christianity. I don't believe in the literal truth of the Gospels, and I'm not even convinced that Jesus even existed. What surprises me is that so few Christians are critical of religious dogma. You can sum up the key Christian dilemma as "Who would Jesus bomb?"
Like Christianity, Islam has various sects with different views and degrees of fanaticism. Terrorists who commit suicide attacks clearly have total faith in their fanatical form of Islam. The leaders of their particular brand of religion have cherry-picked the themes and passages from the Koran that will inspire and motivate their campaign of murder and destruction.
I think you can make the argument that this is much harder to do with the Gospels of Jesus Christ. From my perspective, the Gospels are a portrait of Jesus, the man. Jesus would not condone harming anyone. Jesus would not kill anyone for any reason. If he was attacked, he would turn the other cheek. In the end (at least according to the story), he allowed himself to be put to death as a form of civil disobedience. Mystically, there's a lot more to the crucifixion of Jesus, but sticking to reality for the moment, it was civil disobedience.
There's evidence that early Christians followed in the mythical footsteps of Jesus. They fought Roman oppression with civil disobedience, not with military power or terrorist attacks.
When the Roman emperor Constantine became the first sponsor of Roman Christianity, the reasons for his conversion were less than ideal: Constantine was said to have seen a Christian omen of victory on the eve of a great battle in 312 CE. From that day forward, Christianity merged the Roman devotion to war with Jesus's principles of peace and love. Unfortunately, very few Christians have been willing to concede that the two philosophies are diametrically opposed.
If we were a truly Christian nation, we would have no guns, no death penalty, no military and no security forces. Yet Christian fundamentalists are most likely to support the use of military force and the death penalty (and don't even think about taking away their guns). The only lame excuse I've heard from Christians in support these "choose death" policies is a single passage from Matthew 22:21:
They say unto him, Caesar's. Then saith he unto them, Render therefore unto Caesar the things which are Caesar's; and unto God the things that are God's.
Talk about cherry-picking. Instead of seeing the Jesus of the Gospels as a Gandhi-like figure, most Christians (fundamentalist or otherwise) prefer to blindly follow their religious leaders in the opposite direction.
Is Christianity consistent with killing people, even in self-defense? Until Christianity resolves this little dilemma, it won't even be internally consistent, let alone philosophically persuasive to reasonable people. I suspect that most Christians have never given this question a second thought. From here on, I shall refer to those Christians who favor the way of the gun as "Romans".
To me, the answers to the deep questions of philosophy are pre-requisites for life itself. No doubt, if I lived in the Dark Ages, I would probably have been a friar or something. You may have no interest in philosophy. To the extent that your life is brimming over with the business of day-to-day survival, that's excusable. But when someone else offers to do your philosophical thinking for you, please decline.
