Antitheism

[Excited Penguin]

Without the belief in the gods, the religious institutions and observances wouldn't exist(when talking about theistic religions).
Without the religious institutions and observances, the belief in the gods wouldn't make any sense.

You think that everyone filling the pews believes?  Been to mass recently?  The institutions and observances have a life all their own, apart from belief, as the swarms of "cultural catholics" such as myself ought to make clear.

The majority believes. If they didn't, the non-believing minority wouldn't feel the pressure to lie about it, or put up with it for that matter. You're distorting the facts to fit to your views, just so you can continue to argue with me. You're being irrational. I can't possibly win an argument with you guys if you're going to be like that. I have better things to do.

There's a guy out there in the world, let's call him "Steve", who believes in a god named Bob, and he thinks that Bobgod loves him.  He's pretty sure that Bobgod has a single command.  Don't be a dick.  Now, does Steve really need an institution or list of observances to make sense of his belief in Bobgod?  I don't think so.  He's just a guy who believes in Bobgod, Bobgod loves him, and he's trying his best to avoid being a dick.

(Emphasis mine.)
Yes, he does. The concept of god doesn't make any sense on its own.
