This was by a Christian site?
This is one of those comics that both sides would think it's promoting their beliefs. I was surprised by the tag at the bottom, because I was sure it was from an atheist. Then again, if they wanted it to look more like it's from a Christian viewpoint, the sides should have been reversed, with the Christian getting the last word, as if correcting the atheist.
One commenter on LOLGod.blogspot.com called this a false analogy, and that the Christian was corrupted by a virus which spreads itself from person to person. I'll agree, considering we have the same operating system, and the religion is given to us later on. Theists can substitute "virus" for "software", I don't care.
