people that believe that Israel should be destroyed and Israelis killed, partly because of the damage that they have done to Palestinians
Nobody important seriously believes this. Not even Hamas. Well "Israel should be destroyed" is a popular position, because that's calling for an end to Israeli Apartheid. "Push them into the sea" rhetoric died in the 90s.
“Israelis completely support what their government is doing”
They do though. Specifically 80% of Israelis and 88% of Israeli Jews.
