This is not a bad suggestion. HN folks tend to be "anti" - I think that also is in part isolating. So many / most gatherings of folks don't meet the HN purity / behavior / etc standards (church groups / political groups etc).
As a note I went to church every sunday growing up - my parents (not religious) did it for exactly the reasons you described. Because we weren't religious there are some things that aren't a good fit even if its with other kids (confirmation meetings - I was very reasonably asked not to attend after asking questions because I was confused about the whole thing). There is a wide range of religious orthodoxy as well - plenty of mellower denominations.
