Because Hamas is responsible for some of those 401 deaths too, SYnapse...
Because, as I sent not one but two links to you on, Hamas not only has been confirmed to use human shields--which, whatever you think about them, DOES raise the death toll--but CELEBRATES the use of human shields as the practice of "noble, jihad-loving people."
If you accidentally set your baby down behind my back wheels and I accidentally back up over it, *I* have just killed your baby, but YOU, for putting it there in the first place, could potentially be sued for child endangerment, reckless endangerment, child neglect, gross negligence, and potentially even be viewed as complicit in a manslaughter charge.
Now, if you INTENTIONALLY put that baby behind my back tire, because you'd rather those tires hit the baby first before it hits you, then you REALLY have some moral and legal culpability.
Hamas is responsible for some of those 401 deaths via human shields, which they have not only been found to use but admit to and, as shown in the video clip, CELEBRATE using. That doesn't mean that you have to necessarily diminish your blame of Israel for the 401, but it does mean that I think you should hold Hamas more complicit than you do...and the United Nations, by condemning their use of human shields, seems to be of that mindset as well.
You CAN blame two separate groups and their differing actions for one tragedy, you know...it isn't Blame Israeli Misfires or Blame Hamas all the way, you CAN blame both...
