Religion forces every individual to take responsibility. Specifically, take it away from yourself and give it to God. If we had to be accountable for every one of our actions, we'd be crippled with indecision. But with religion pointing the way, we can feel confident in our choice to picket our children's elementary school when we find out the art teacher is gay.

Whether or not you believe in God, you must believe this: when we as a species abandon our trust in a power greater than us, we abandon our sense of accountability. Faiths… all faiths… are admonitions that there is something we cannot understand, something to which we are accountable. With faith we are accountable to each other, to ourselves, and to a higher truth. Religion is flawed, but only because man is flawed. The church consists of a brotherhood of imperfect, simple souls wanting only to be a voice of compassion in a world spinning out of control.

I could go on, but the point is clear: religions make explicit claims about reality—about what exists and happens in the universe. These claims involve the existence of gods, the number of such gods (polytheism or monotheism), their character and behavior (usually loving and beneficent, but, in the case of Hindu and ancient Greek gods, sometimes mischievous or malevolent), how they interact with the world, whether or not there are souls or life after death, and, above all, how the deities wish us to behave—their moral code.
These are empirical claims, and although some may be hard to test, they must, like all claims about reality, be defended with a combination of evidence and reason. If we find no credible evidence, no good reasons to believe, then those claims should be disregarded, just as most of us ignore claims about ESP, astrology, and alien abduction. After all, beliefs important enough to affect you for eternity surely deserve the closest scrutiny.

Our particular principles of religion are a subject of accountability to our god alone. I enquire after no man's and trouble none with mine; nor is it given to us in this life to know whether yours or mine, our friend's or our foe's, are exactly the right.

In the end, religious investigations of “truth,” unlike those of science, are deeply dependent on confirmation bias. You start with what you were taught to believe, or what you want to believe, and then accept only those facts that support your prejudices. This is the basis for the theological practice of “apologetics,” designed to defend religion against counterarguments and disconfirming evidence....In contrast, science has no apologetics, for we test our conclusions by trying to find counterevidence.

If you’ve made it this far in starting your own religion it means you’ve assembled a nice group of hopeless people desperately avoiding the Uncomfortable Truth by studying a bunch of bullshit you’ve made up, ignoring their friends, and telling their families to fuck off. Now it’s time to get serious. The beauty of a religion is that the more you promise your followers salvation, enlightenment, world peace, perfect happiness, or whatever, the more they will fail to live up to that promise. And the more they fail to live up to that promise, the more they’ll blame themselves and feel guilty. And the more they blame themselves and feel guilty, the more they’ll do whatever you tell them to do to make up for it. Some people might call this the cycle of psychological abuse. But let’s not allow such terms to ruin our fun.

The enemy of accountability is ambiguity

Gods need take no responsibility for anything except genesis. Gods accept everything and thus accept nothing. Gods must be identifiable yet remain anonymous. Gods do not need a spirit world.

You should thank the gods for making you strong enough to survive what you cannot control, and only responsible for what you can. [33] The gods have released you from accountability for your parents, your siblings, your body, your possessions – for death and for life itself. [34] They made you responsible only for what is in your power – the proper use of impressions. [35] So why take on the burden of matters which you cannot answer for? You are only making unnecessary problems for yourself.

At some fundamental level, religion does not allow for compromise. It insists on the impossible. If God has spoken, then followers are expected to live up to God's edicts, regardless of the consequences. To base one's life on such uncompromising commitments may be sublime; to base our policy making on such commitments would be a dangerous thing.

Theists’ typical response to these failures (i. e., of prayer to affect rates of healing) is to say either “God won’t let himself be tested” or “That’s not what prayer is about: it’s simply a way to converse with God.” But you can bet that had these studies shown a large positive effect, the religious would be noisily flaunting this as evidence for God. The confirmation bias shown by accepting positive results but explaining away negative ones is an important difference between science and religion.

"I am accused of mysticism. I do not, however, hold myself responsible for the fact that man has, everywhere and always, spontaneously developed religious forms of expression, and that the human psyche from time immemorial has been shot through with religious feelings and ideas. Whoever cannot see this aspect of the human psyche is blind, and whoever chooses to explain it away, or to "enlighten" it away, has no sense of reality."

Religion is heavily laden with the kind of confirmation bias that makes people see their own faiths as true and all others as false. In other words, religion is replete with features to help people fool themselves.

But none of this criticism of science makes religion even a tiny bit more credible...
In contrast, religion has never been right in its claims about the universe—at least not in a way that all rational people can accept. There is no reliable method to show that the Trinity exists, that God is loving and all-powerful, that we’ll meet our dead relatives in the afterlife, or that Brahma created the universe from a golden egg. Lacking a way to show its tenets are wrong, religion cannot show them to be right, even provisionally.
