There are non-combatants in this conflict that are bad people. They cheer on the extermination of others. Sometimes that's Hamas or the PLO (they run a fund that gives stipends to families of terrorists). Other times it's certain Israeli Jews who encourage conflict while not risking their own necks because they can claim a religious exemption from military service. They seek an Israel without Palestinian territories, or for that matter Palestinians at all (aka ethnic cleansing).
I'm not saying that non-combatants should be targeted. At the same time, I am saying that just being a civilian does not mean someone lacks blame.
