So why should i or anyone else care how many palestinians die?

Do you really mean that, truckerdave? Would you support ethnic cleansing of all Palestinians? Would you support the elimination of Palestinians so we won't have to be bothered with them any more? When we get to the point where we don't care how many of a particular group of people are killed or die, it's not a very big step to get to the idea of genocide. You wouldn't support that, would you?
