I've never read any of the holy books in their entirety. I've read bits and pieces of some, the Christian Bible more than any other, but not very much of any of them. I've had people tell me that if I've never read insert your favorite holy book here, that I can't possibly begin to comment on it's truth value. I'll set aside the idea that all of these supposed holy books have one thing in common: none of them have evidence to back up the miracles and deity to human communication that all of them claim to have happened. I'll do that because I can, for the sake of argument, assume that a god does exist and still have many monkey wrenches to throw in the gears that are their arguments.
There isn't a need to list them because even if none of those can convince you(and I know they won't) I can take a step back and say that even if any of those gods do exist, I wouldn't worship them. I would curse that god every day, telling him he is a coward like none other. I would dare him to show his face. Any theist who has ever heard me say that always replies the same way; when you stand in front of god, you WILL bow before him. I have always thought that could mean that I would either be so scared or awestruck that I would have to bow in his awesome presence or that he would force me to bow with his godly power. Maybe it's the tone of smug glee that comes standard with the aforementioned statement, but I really feel theists believe their god isn't above forcing someone to bow before him. That is a scary thought.
