Sorry, but "selective" targeting in a war is not an option when the enemy uses civilians as shields or the civ turns terrorist. If you were engaging them, do you think you could tell the "good guys" from the bad?
Some people have terrible moral blindness (and historical, and factual...) when it comes to Israel and the Palestinians. There is plenty of info out there so that people can inform themselves properly. There is no excuse for remaining ignorant.
