And for the record, I agree with that statement. Palestinian and Israeli lives matter.
All lives matter. Black lives matter. Asian lives matter. Latin lives matter. Blue lives matter. Babies' lives matter. Yes, even white lives matter. The only thing that shouldn't matter in this conversation is the color of a person's skin or their religious beliefs.
Killing innocents is wrong, period. And when Israel is done doing whatever they're going to do (and are already doing) they'll be wrong for killing the civilians they will inevitably kill. Nobody should logically be able to condemn Hamas for killing innocent civilians and then claim that Israel somehow has a right to do it. Innocent is innocent.
Now, if you're a soldier, that's another story. In the case of Gaza, it will be difficult if not impossible for Israel to kill the enemy without collateral damage. Civilians will die. Ideally not, but war is hell which is why it should always be a last resort. I think at this point that we, as Americans should just hope that Demented Joe doesn't bumble or gaffe us into being involved in a shooting war or worse, a war where our soldiers' boots are on the ground.
