1) The horrible things in the Bible need to be publicized as much as possible and
2) The blow is softened just enough by making fun of Walmart for removing Jon Stewart's book from the shelves.
So talk this thing up. As Aaron says:
I hope this petition makes national headlines too. The way I figure it, the only way this thing can make national headlines is if enough atheists talk about it to where it catches the attention of the Christian mainstream population, at which point the Christians will likely start a counter-petition or something, and then Fox/Cnn/etc... will pick up the story based on the surrounding controversy.
