Until you understand that for a very large number of Israelis Palestinians are sub-human you will waste your efforts trying to argue with Israelis based on rationality or ethics. They are racists full stop.

The reason is simple: it’s the combination of forced military and being the descendants of a generation that migrated and ethnically cleansed Palestine are overwhelmingly potent sources of indoctrination. Most people tend to assimilate and therefore they will blend into the Israeli military (and you see what kind of ethics they have) and most people find it difficult to condemn their parents and grandparents as genocidal monsters so instead they will favor whatever narrative absolves their lineage.
