Okay, I'll try my best to answer.
My immediate family, none are religious. I am familiar with the facade, as my partner's family resonates with your description. It took me a year just to realize the underlying dysfunction they have--pretending all is fine by never talking about anything not superficial. But my immediate family is very forthcoming, honest and upfront--as you can see in my behavior on here. Family gatherings have a significant level of genuine harmony and love.
We came from a very dysfunctional past. But we all made strides, and it paid off. Any difficulties are right on the surface, and most are "mental illness", or rather what I think is the difficulty which comes significant mystical development in past lives. I can't review the sources you provided right now. But I will get back to you.
I understand what you're getting at. And the best answer I can give right now is that they do not reflect the common dysfunction of America. Self-discovery is highest on the list for everyone, but they all have different methods. This really is an honest answer. If you would have asked me four years ago, you would get a very different answer.
Let me know if that is sufficient response.
