The takeaway: it's not a 'poor cross section,' it's a normal sample of the human population.
I should have clarified to mean poor ideology, not individuals. Of course, I acknowledge that rating of "poor ideology" can easily suffer from white-tower syndrome, because of course the version of Christianity to which I subscribe is the
correct one.

I mean the whole discussion on "God rejected me" stems from the most fundamental axioms or core beliefs of a world view. I'd personally say that doesn't align with the overall story of the Bible - sure there are individual stories of rejection, but the overarching theme of the Bible is God being faithful to humanity (first by proxy through Israel, then in general through Christ)
despite humanity basically behaving as if they were themselves gods and could just do whatever they want.
I mean so much of the Gospels at least is Jesus challenging the prevailing worldview and specifically showing how God cares for the marginalized and rejects the self-righteous. Jesus teaching also showed how it's not about the religious practices, but about the contrition of the heart. Essentially, knowing that God is God, and you are a human, and that, despite living in a corrupt world where we personally and we collectively as a society have tendencies to destructive and harmful behavior, God in fact doesn't reject us - but at the same time, God gives us the freedom to stay away if we want. We aren't automatons.
We choose to try to emulate Christ not out of obligation, but out of love. We put our own preferences and desires second, not because those things give us salvation, but because we are sure in our salvation already and are free from wondering "am I good enough?"
Being a Christian isn't about "going to heaven when you die
1" even though that does appear to occur - the main message of Christ wasn't "you get the kingdom of heaven when you die" it was "the kingdom of heaven is
here." It's about having a restored life now, regardless of the physical circumstances. It's "free" in the sense that you can't do anything to earn it - but it isn't "free" in the sense that you have to die to yourself; Mainstream American Christianity especially doesn't seem to be willing to do that - and even other offshoots - people want to do what "makes them happy" even though personal happiness has never really been something we are to strive for as far as I've read the Bible.
My heuristic is: does what I believe put God first? Does it put other people next? Self comes last, if at all. This is very different than "self first" which is often promoted these days. And note that "self last" doesn't mean "self neglect" - it just means, in all you do does it reflect the best of things, or is it just doing what you want?
1This is one of the worst teachings of "American" Christianity - that it's only about your personal relationship with Jesus and kind of an existential insurance policy. It's taking Pascal's Wager at its worst interpretation.
