A quick point about what a religion "teaches"
What a religion teaches, is not based on what certain groups within that religion says, it's based on what the supporting documents for that religion teach.
What I mean is this, the Bible teaches adultery is wrong. I don't care how you slice it, I would be happy to debate anyone on the issue, the Bible "teaches" that adultery is wrong. So, some could deny this point, every church could stop teaching it's wrong, but in the end, the Bible still "teaches" it's wrong, regardless of how many "Christian" adulterers there might be or how accepted adultery might become.
Now, I freely admit I have not read the Koran, so I cannot speak to what Islam teaches, but I can say this. It's not about what moderate, or fundamentalist say, it's about what the Koran "teaches".
The point being, we should not confuse the actions of a group within a religion with the teachings of the supporting documents. If (and again, I don't know) the Koran "teaches" that all Jews should be killed, along with other infidels for example, then it is a religion of "hatred and violence". If on the other hand, it teaches, that you should love your enemies, and be kind to those that spitefully use you, then the "religion" doesn't teach hate and violence, regardless of how some in that "religion" behave.
Finally, what the supporting documentation teaches, is not based on a single verse, but what it teaches as a whole. There are a whole set of "rules" and principles involved in the proper interpretation of the Bible. (Though I have not read the Koran, I have spent vast amounts of time reading the Bible over the last twenty years of my life) If those are followed, "Most" people can arrive at similar positions, even on rather obscure or difficult issues; and most of the time when they don't, it's because they have an agenda.
So, I've said all that, to say this. It should not be that difficult to determine what Islam (the Koran) teaches concerning the Jews and the infidels. It just takes some time to do so. Whether it teaches, peace and harmony, or hatred and violence, or something in the middle, how people act, or what they say is irrelevant, what it teaches it teaches. (The same is true about the Bible, or what ever other religion you wish to address.)
