That feels odd to me. Recognizing the value of community doesn't seem at odds with a rejection of supernatural entities. Likewise, I don't see the value of evangelizing my agnosticism to communities of different structure. Pluralism to me is an essential component of a society as large as our current one.
Maybe there is stuff just too big and complex to understand and perhaps that is the essential truth
Speaking only for myself here, but I don't need a god to acknowledge that our material and social world in complex beyond comprehension. At the same time, I also don't feel the need to have a being in my life that does comprehend all. It is enough for me to know the limits of my knowledge, and to scope my life within that context. Even more to the point, I find that the quest for "one essential truth", to the point of denouncing different conceptions of the unknown, is in itself detrimental to society.
So as to your question, I believe there is tremendous value in allowing people to be secure in their religion. It provides security, comfort and community for them. And I believe the recent surge in anti-scientific movements is in part motivated by (atheists') relentless attacks on the core tenets of other communities. Gods have always resided in the unknown, not in the unknowable. As the limits of our knowledge progresses, so have gods changed their shape. But by attacking faith on the unknowable, people have created much more animosity and defensiveness than should have been necessary.
