I think you are the idiot here. If Christians or Atheists committed the same number of atrocities, we would all agree with your sarchasm 100%. However, that is not the case. We don't have sleeper cells of atheists and Christians plotting to kill as many innocents as possible. You can't say the same thing about muslims and the islamic faith: they most certainly have groups around the world who are intent on killing innocents - in fact, it's one of the tenets of jihadi belief! Wherever the Islamic faith butts up against any other civilization, there is trouble. 100 out of 100 times. Does that mean anything to you?
I will never understand why people like you can't admit the obvious. Instead you want to play games and try to find equivalence between a couple of Colorado crazies and the hundreds (thousands?) of attacks done by Muslims. Good luck trying to win hearts and minds with that approach. People aren't as stupid as you think they are.
