Point: More people have been killed in the name of religion than any other cause.
Counterpoint: The killers would have found a reason to kill them anyways.
No. No! NO!
I hate this argument. It is logically weak in so many ways, but its apparent simplicity captures too many people.
You see, it suggests that murders in the name of religion aren't so atrocious, because they could have been for any reason. This disgusts me. The Holocaust was such a horrible thing because - among other reasons - millions of people were killed solely because of their religion. Saying "Oh, Hitler would have found another reason" detracts from the severity of the crime.
And it's just a stupid thing to say - if six million Jews had actually been six million Christians, the Third Reich would not have brutally slaughtered them all. If Israel was an Islamic nation, there would be no conflict with the Palestinians. If America was a Muslim nation, the terrorist threat would be nonexistent. If 15th Century Spain had Buddhist monarchs, the Inquisition would not have occurred.
