Without jumping over to that other thread, I'll just quickly state that if someone has a delusion, they are not aware of it generally speaking. To them that delusion is not a delusion, but actual reality. All parents teach their children what they believe is reality, even if to others that reality is seen as delusional. Are you suggesting there be a central authority to decide what is truth and reality for people to rightly believe? Isn't that your central complaint about the church?My delusions are for me to overcome but I think we shouldn't impose any on children, which was why I started the other thread.
Besides, everything we believe to be true ultimately is a delusion anyway, even what I am saying right now. At best we humans come together and create a "consensus reality," as shared truth that we collectively agree upon and put all the mechanisms of socialization to work to keep that vision a cohesive whole.
What you have then is functional truths, not absolute truths. And those functional truths shift and grow as culture as a whole moves along its path, like an organic blob feeling its way through the environment. Meanwhile, culture spreads its mass delusion to all its children though its stories and media, the arts, etc. So, parents teaching their kids their delusions is just being part of how that cultural organism sustains itself.
Religion is an extension of culture. Like Ian Malcolm in Jurassic Park famously said, "John, the kind of control you’re attempting simply is… it’s not possible. If there is one thing the history of evolution has taught us it’s that life will not be contained. Life breaks free, it expands to new territories and crashes through barriers, painfully, maybe even dangerously,"Of course one can live with as many delusions as seem appropriate, but not when they seem to affect others so much - which undoubtedly many religions do.
Just substitute culture for life above, and, "I’m, I’m simply saying that culture, uh… finds a way." Honestly, changing the guard, changing the narrative, changing the delusion, is all part of it, and doing the very same thing religion is accused of imposing on us. We impose our realities on ourselves. Culture always finds a way....
