Im sad to say these reactions don't surprise me at all. Noone but the DUmmies base their entire outlook on life on voter registration. And in the case of pain, suffering and death, it doesn't matter if you are athiest, Christian, Muslim, or Jew. It doesnt matter if you are Conservative, Liberal, or Green. Once you are dead, the thing that made you, "you" is no longer of this world, and that missing element is a loss for someone out there. Have some level of respect, at least for the surviving familiy and friends if you can't bring yourself to show at least a shread of common decency for the recently departed.
Grave pissing doesnt make one a man, it proves that one isnt man enough to overcome hate.
