I occasionally get asked how I could be so arrogant as to be an Atheist.
And my response is "The same way you can arrogantly be an Atheist."
This unerringly elicits an angry denial and a declaration that they are a Bible believing, God fearing Christian.
"So in which god do you believe?" I ask.
"What do you mean which god?"
"Well do you believe in Ganesha, Neptune, Osiris, or Jupiter?"
"No! None of those! I believe in the one true God. The Christian God!"
"Oh so you believe in the Christian god, Yahweh, but not any of those others. Did I hear that right?"
"So would you say that you are not absolutely certain that those other gods don't exist? Or are you still open to the possibility that someday you might believe in one or more of them?"
"What kind of a stupid question is that? I KNOW they don't exist, they are only myths. Nobody in their right mind would believe in something so ridiculous."
"I see. So let me ask you, how can you be so arrogant, so filled with certainty that you would dismiss the beliefs of people who died in battle with a prayer to these gods on their lips, who dedicated their lives to proselytizing on their behalf, in other words to be an atheist when it comes to so many gods, who have been worshiped by so many millions of people?"
That is pretty much the end of the discussion.
Oh there is some sputtering, occasionally some name calling, but all in all the actual conversation is finished.
