Not at all. If the Bible and/or the teaching and example of Christ commanded the extermination of unbelievers, I would not subscribe to that system of belief and would be just as harsh on it as I am on Islam by virtue of the fact that its book and the teaching and example of its prophet DO call for my extermination by virtue of my nonbelief in that system of belief.
I will grant you that religion can be a lot like Linux in that a person can take a basic idea and form his own just-right-for-him system out of it, with actual mileage varying on a case by case basis, but for the purpose at hand the only reasonable way to evaluate a religion is by the contents of its book(s) and the teaching and example of its founder as polling every individual believer is not practical, and this is not Microsoft where you take it Bill's way or you do without.
Luke 19:27
