"Millions of people choose to believe God under FAR worse conditions."
True words. Perhaps one of the "worst" conditions - as noted by Richard Dawkins - is "accident of birth".
Belief systems thrive in places where they have already been established as the "norm". Individuals grown up taught from infancy about "God's" will. Each generation of "believers" shapes those beliefs to meet contemporary outlooks. Which "sacred book" does your community generally accept as "truth" and/or "the Word of God/Allah"?
"Truth" and "God's will" has the least to do with it.
A notable trend in more recent and current attempts to make ancient teachings palatable to modern humanity has been to give those teachings a decidedly "reasonable" appearance, moving from stark announcements of "Thus saith the Lord" to "Let's reason on it". Chuck Russell is a prime example of the 19th century attempt to "contemporarize" an old, old message.
No matter how much you spin ancient patriarchal religious teachings, they remain just that: ancient and patriarchal. Such spin evaporates under the very "method" it tries to use: "Reasoning".
