Yes they are. It's the same groups that have been campaigning to end the occupation since before October 7th. It's not a majority or even close to - two-thirds of Israelis support the continuation of the war. But saying "no one" is an absolute falsehood. And, I think propaganda and misunderstanding of the situation on the ground is also a large part (in addition to, yes, some large amount of pure racism and violent vindictiveness that says it's okay if Palestinians are dying because they are bad.)
The wheel you're currently cranking on, is the same wheel that was turning right at the beginning of Israel, and managed to turn its way from "all the Nazis are wrong and evil" around to "the Jews are always the victims about everything" and has now arrived itself at "Israel can do anything it decides to and will still be the victim" and now, on the other side, "all the Israelis are always wrong and evil" is emerging into view coming in the other direction. I am telling you that no matter how hard you crank that wheel, on whichever side, your activity will never crank you around to arrive at a world that is peaceful or just.
(I know I said I'd stop after saying my bit; I just wanted to say a little more on it and shoot down the absolutely false idea that no one in Israel opposes the war on humanitarian grounds.)
