The same argument could be made for preppers, who plan for an event that is about as likely to happen in their lifetime as is the existence of the invisible sky fairies you write about.
That statement isn't logical.. or rational. Lifetime events are a statistical probability assessment (math), but the existence of a deity is a purely logical analysis and is absent statistics.
Allowing a bit of wiggle room and addressing the point I think you're trying to make, your statement is equally true and false at the same time.
Here are some points to consider:
*Many preppers live in geographical areas prone to earthquakes, large fires, or hurricanes.
*Most preppers, about 95% of them based on my experience, are also religious. That said, it is also important to realize that the irrational levels of religious people range from the "its family tradition on the holidays" to "the rapture is upon us and my pastor would never molest my child"
*Recent events in the past couple decades have surprised everyone (911, Indian Ocean tsunami, Japan tsunami, Riots in USA, Covid lockdowns, Attack on congress, Ukraine-Russia war, etc)
*A smaller subset of preppers (like me) are not worried about the statistical probability of an catestrohpic event any more than we are worried about our home burning down. I do have homeowners insurance, do you?
There are other things to consider, but generally your statement has merit. The vast majority of preppers believe unlikely and even Hollywood ridiculous events will happen.
As to indoctrination, consider your children who are being raised in an environment of irrational fear and self-denial, and who are likely to be the target of other children their age because of these differences.
What are you talking about? I'm imagining a black girl wearing a burqa in an Alabama public school.. but I'm guessing that's not what you mean.
