I wasn’t born into a religious family either, so there was not much of a process for me.
I do find it interesting, however, that when the negative aspects of religion are brought up, or when certian persuasive arguments are brought against various beliefs, apologists will often say things like “well what harm does it really do anyway?”, “What’s wrong with just letting people believe what they want?”, and the ever popular “Why make such a big deal about these beliefs?”
When pressed into the corner they try to act like various religous beliefs are “no big deal”, and thus should just be left unchallenged.
The flaw to this claim is obvious. If they are no big deal then they should rightly be challenged, since why should we leave false beliefs that are no big deal unchallenged, but more importantly, they very obviously ARE a big deal. People center their whole lives around these beliefs and get hugely emotionally invested in them, their family lives are linked to them, everything.
If these beliefs were “no big deal”, then people like yourself wouldn’t have such a hard time coming to grips with them, and people wouldn’t be so upset when you challenge them.
For whatever psychological reason, which I cannot address because I have not experienced it, these beliefs become very central to a person’s sense of self and place in the world and their emotional comfort. That fact alone speaks to the importance of gaining a better scientific understanding of belief. This is a real, serious issue and condition of the human psyche.
