One thing I've noticed is how each community I've personally had experience with has had a definite culture or identity that, once established seems to be very hard to break, and that it might be very important to have the skills needed to 'shop around', and let oneself OUT of a relationship with a community that doesn't work for you. So, not only to be able to establish ties, but to remember that we don't have to tie it to some notion about re-forging the 'ancient tribes', in which we're stuck with whatever one we've got. (And as that goes, even in a single town, there'll be various subsets.. you might see them as cliques, but ultimately you need to settle in with the people you fit with somehow)

It's like the shorthand I've used for Career choices. Every occupation comes with some BS.. you just have to find the kind of BS that you can deal with..

You need to get out of not only a community that doesn't work for you, but also from one that isn't going to work for anyone. As per below.
PS- I don't agree that every occupation comes with some BS. My mother and 2 brothers are teachers of music (performance). There's zero BS in music and its teaching and if there was it would quickly get binned. Sure re some of its practitioners. Very high BS level in the instrument (esp piano) sales biz though.
