You are putting too much weight on intention. Intention doesn't matter. Results do. True intentions are rarely stated. What were the stated US intentions going into Iraq? What were the stated Nazi intentions going into Poland?
The current conflict has killed 192 in gaza including 58 children. It is unacceptable for Israel to kill children - even if killing children wasn't the "point." Israel's use of arabs as human shields was unacceptable even if the "point" was not to endanger arabs (https://www.theguardian.com/world/2005/oct/07/israel).
The issue is that the totality of the evidence - civil rights abuses, crimes against humanity, disproportionate civilian deaths, a system designed to propagate an ethnically clean state, a system designed to expand that ethnically clean state, the continuation of bombardment even after calls for truces - make clear that dehumanization and apartheid are being conducted by the State of Israel whether those intentions are stated or not.
There have always been supporters of and reasons to support atrocious events in history. Folks rationalized slavery in the US for reasons. The south african apartheid was worth it from some people for some reasons. Hitler had his reasons to go into Poland. The US had reasons to otherthrow Sadam. The presence of reasons doesn't automatically justify actions if the actions are inappropriate. History will see the Apartheid by Israel. People see it now.
