Lol, on what grounds don't you agree? Do you know these guys? Have you talked to them?
In my very brief military service, as part of the (Israeli) army jail punishment I was sent to guard "camp 16" ("makhaneh shesh-esreh"). That's one of the facilities where IDF puts Palestinian terrorists. So, I've seen and heard some.
In early 2000's (I think it was 2003) I worked as a waiter in Caffe Hilel in Moshava Germanit district of Jerusalem. It was the one which was blown up by a dude from Eastern Jerusalem who worked there in the kitchen. The guard died and another waiter died. It was right before my shift, so I didn't catch the event itself, I came right afterwards. There were about a dozen of people wounded because the glass at the entrance shattered by the explosion and spread all over the place.
Anyways. I knew the terrorist guy from work, obviously, ad well as I knew plenty of other Palestinians both from the occupied territories, from Gaza, from Eastern Jerusalem or somewhere inside Israel, like Ramle / Lod.
And here's the hard truth about it: unless you are someone educated, someone who got to travel a bit, speaks English to a degree that you can independently read / watch the news, you are the terrorist material. And that's the vast, vast majority of population of Gaza. They don't know any better, and they live in the world that westerners cannot even imagine. They have no idea humanism was invented. They have no idea human lives in general are worth something. They really think that westerners are stupid and weak because they care so much about their lives. The feeling is compounded by disgust, because from their perspective caring about one's life or well-being more than caring about some absurd superstition is an affront to their understanding of modesty.
These people live in a hierarchical world where boundaries are set by gender, nationality, religion. Your worth is determined by you being born into a particular nationality, beside other things. Jews are simply inferior in their world view. The fact that they even aspire to be on the same level with Arabs is an affront to those traditional Arabs. It's like a torture to them to have a Jewish manager, or to comply with what a Jewish police officer tells them to do.
This is not about religion. Arabs living in Gaza, for example, wouldn't recognize Jewish converts in the US as Jews. It's about ethnicity. It's not about anything you can consciously change about yourself. Even if you were a Jew who converted to Islam, you'd still be inferior in their eyes.
So, do they want to kill all Jews -- you bet they do! They wouldn't bat an eyelash telling you how that would be a miracle from god if all Jews died a painful death, all at once. I mean, unless you are talking to someone who was exposed to the idea that killing people based on their ethnicity is bad. Most of them either genuinely don't know it, or despise people who think that way. Not everyone would take up arms to do it, but in their world view, anyone who does it is like a saint...
