Probably 90% of Christians have no idea of what is in their bible because they don't and never have read it. They certainly have never made an in depth analysis of Jesus' teachings versus Paul. Paul versus James, Peter, etcetera. If they have read it, it was after indoctrination by the likes of Jimmy Swaggart, Billy Graham, or the Catholic Church, or whoever. If you set Jay Leno up outside a Baptist church or a Catholic Church and he did a Jay Walking segment it would be worse than when he set up at a college asking the students who fought in the Spanish American War.
That being the case they accept whatever a preacher tells them and don't realize that some of the bible (mostly in the New Testament) has been doctored, redacted, added to, and even forged. When you find something in a writing that doesn't fit or make sense it is time to wonder who put it there and why.
There are several letters attached to the gospel that are attributed to a single writer that while they contain a good bit of truth, the main gist of which was to corrupt the doctrine of Jesus as was noted by no less than Thomas Jefferson.
Patriotism (and religion) is the last refuge of a scoundrel.
