I was concerned with. I was asking about the legitimacy of their method of warfare, which is to target their attacks against innocent civilians. THAT I do have a problem with.

Using your line of logic, if I did something that pissed you off enough, you would be warranted in abducting my child and torturing him -- as a response to something I did. Because I provoked you and started it.
Sorry, but I can't agree with that kind of reasoning.

I feel equally appalled for and bad about the deaths and injuries of innocent people on BOTH sides of the Israeli-Palestinian conflict.
It's an unfortunate fact of warfare that bystanders sometimes get caught in the crossfire. But I take issue when they are specifically targetted rather than being collateral damage.
