You haven't been watching the news. I think the score is about five to one at last count but that doesn't include the hundreds killed in the last few days. Of course, it's Palestinians on the one hand and Jews on the other--that makes all the difference.
One side is justified and the other isn't.
The Palestinians are murdering Jews. The Jews are trying to defend themselves against the murdering Palestinians.
There is no moral equivalence between murder and self-defense.
Maybe the you and the Palestinians really are too uncivilized to tell the difference.
No, it's (mostly) "gunmen"/soldiers on the one side and civilians on the other. Yes there has been some collateral casualties. The difference is one of deliberately targeting civilians and accidently harming them while defending yourself against armed men, who sometimes hide behind, literally, those civilians.
If Israel wanted to just kill Palestinian Arabs, they could have not sent in their soldiers to dig them out house by house, but rather backed off and called in Arty and Air Srikes. Now understand some arty has been used, but AFAIK no air, other than helicopter gunships. They are perfectly capable of building Daisy Cutters and have C-130s available to deliever them, if they just wanted to kill Muslims.
