When people focus on Netanyahu and the settlers that is a way of focusing on individual personalities while leaving structures unaccountable which is what is always done with systems of oppression
Given the fact that the scope of the horrors that is inflicted on the Palestinians is unavoidable, even for people who take a staunch Pro Israel stance. And so one of the things you have seen is a rhetoric that isolates individuals from structures of power. So you will hear "well I oppose Netanyahu and his current right wing government". Or "I think Israel is a major ally and I support its right to self defense but I think the extremist settlers go too far". The thing is, Netanyahu, and the extreme settlers didn't come out of no where. They came out of a system in place that actively dehumanizes Palestinians and we've seen rhetorical pattern when it comes to structures of oppression in the past.
During the Age of discovery when the genocide of the indigenous populations was taking place and you had certain people like the Dominican priest Bartolome De Las Casas documented those crimes many people in that age said "well we support the colonial project but we condemn some of the extreme abuses that individual conquistadors engaged in". During the abolitionist movement when the horrors of slavery were revealed you had many who defended the system of plantation slavery while condemning the "abuses" of individual masters. Same thing during Jim Crow segregation in the American South where they would condemn the extreme abuses of the KKK while leaving the system itself intact. Isolating individual actors or abuses in a system is a method of whitewashing said system.
Netanyahu and the extreme settlers aren't just a few bad apples. And they didn't just come out of no where. Netanyahu would not be able to do what he has done if all of the other PM's of Israel going back to Ben Gurion himself didn't set a pattern in place. There is a direct link between the ethnic cleansing of the Nakba under Ben Gurion's tenure and Netanyahu's current genocidal policies. And there is a direct link between the apartheid structures put in place in the occupied territories and the violent settler colonialism of the settlers.
