The only difference might be that Christians are perhaps slightly more literate, and maybe more knowledgeable of what the Bible actually says than Muslims are of what the Koran says. The Madrassas teach Muslims to memorize the Koran, but they memorize it in Arabic, and a majority of Muslims do not speak Koranic Arabic.
A lot of both Christians and Muslims are clueless about the core beliefs of their respective religions. Was it Kramer who was unaware that Christians believed in the resurrection of the body, for example? There is rather a lot in the Bible, but I have observed over the years that most of it is never quoted in sermons at all. So it is rather bogus to assume that a majority, or even a significant minority of Muslims believe in the bloodier parts of the Koran as they might apply to live in our times. Islam is officially one thing, but what the believers actually are willing to do about it is something quite different. For the US to declare war on Islam is an insane proposition.
