I guess any violent act committed by a terrorist group (Hamas) would be classed as an act of terror.
Ultimately, however, it doesn't matter to me what you wanna call it, terror or murder or whatever else. Parents lost their kids for no other reason than being Jewish.
I'm not sure whether you are agreeing with me or not to be honest. My original comment was with regard to the hypocrisy people like Barack Obama calling one murder an "act of terror" but not the other.
