Religulous gives us all things to think about-- most particularly, I think, what role religion plays in our society. I think it is worth evaluating if a belief in god does really make one a better person or make the world a better place...
It all begins with: there is a god, god created all things, god is the giver of good; you must believe in god. It doesn't sound like a big deal! Just accept that there is a deity who set the world in motion (and some think god oversaw evolution- doesn't require rejecting science altogether).
But then that begs the question: which one should we accept?
It is ultimately our expectations of god that inform our decision about which god to choose. Do I want everlasting life or the promised land? Do I want to come back as a king or experience Nirvana? Any christian who claims to an atheist that they have blamed god and are angry because they did not "get what they want from god" is not being truthful because if the idea of heaven were taken away from the offerings of christianity, I believe we would see a mass exodus of faithful followers. But of course, that only leads to more questions because IF you have certain expectations of god and, for instance, do expect heaven-- then HOW do you get that?
Addendum: Not all people believe in god because they are afraid of god. Some are afraid of themselves-- they don't think they can negotiate life without the aid of god. Others (liberals, those who do not believe a literal interpretation of the bible) find... hope? in a deity who is leading us toward a better world. Some are seeking internal peace and think seeking god will lead them there. Some are simply afraid of being human and want to believe they have god within them-- this gives them... what? a sense of worth? It doesn't really matter what you believe about god-- but the reasons for believing in god generally surround your expectations of what god should do in you or in the world.
There is one rogue group: Some believe a community of faith is really about the community- having others to work through life stuff with. They are not concerned with god much at all. The problem is that this group has a false sense of community. If they were really honest about what they believe, they would find that their community would turn on them. And it still seems to rest on the idea that the community of faith is somehow more moral than the rest of the world. There is no logic surrounding this argument, it is simply a bias that slips in behind the rest of the brainwashing that comes with religion--the superiority factor: my club is better than your club.
Nevertheless- whatever you decide about which god you want to worship- there is then a series of things to believe. Does the bible teach me what I want/need to know about god? The koran? The torah? Just which book should I follow to learn about god? (More to follow)
