I personally know many people who do care about the truth of their gods. I accept that many religious people do not care so much about the objective truth of their claims, but many do.
There is no "objective truth" when it comes to God. There is only the possibility that our idea of God is true, and our choice to trust in that possibility, or not to.
Secondly, if we have no objective (intersubjectively verifiable) evidence of something and no sound reasoning to support the idea, it has the status of a random guess as far as truth is concerned.
Millions of people believe in the same God-concept and find that it works for them in their lives as it is purported and expected to. That is their "intersubjective verification", and the fact that it does work for them is certainly reason enough for them to continue their belief, especially when they have no proof to the contrary (and neither do you or anyone else).
You seem to be arguing that belief in gods is somehow on a par with taste or aesthetics; just a personal preference. I really wish all people with religious faith viewed it like that, but they don't. Tell it to those suffering from persecution because they have the wrong/no religion or the wrong sexuality in societies dominated by religion.
People persecute other people for all sorts of reasons, and with all kinds of excuses. It really has little or nothing to do with theology. The thing that matters about theology is that the God-ideals we choose to hold both reflect and embolden who we already are. And if that is not who we want to be, or want to become, then we need to change our God ideals.
Put simply, this means that angry, vengeful, violent people tend to believe in angry, vengeful, violent Gods, and then use those beliefs to justify being angry, vengeful and violent. Whereas kind, generous, forgiving people tend to believe in kind, generous, forgiving Gods, and use those beliefs to inspire kindness, generosity, and forgiveness within themselves and others. And all of this is true whether any gods actually exist beyond our trusted ideals, or not. THIS is the "reality of God" that the OP is looking for. And it is a FACT that cannot and should not be denied or overlooked.
