Going way back to the original post, mainly because I'm new here and just getting into the conversation, I really, really don't understand why it is that Christians feel it necessary to convince themselves that there really are no atheists at all. I've seen posts like that many, many times where they try to use twisted logic to "prove" that atheists don't exist.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
