I suspect very strongly that we live in a "post-community" world. There are no communities, and haven't been for a very long time, likely since before your grandparents were in their prime. We have any number of entities that function as surrogate communities, but without the benefits the real thing would provide. Quite often though, they have many of the disadvtanges of those, plus a few extra.

The community you're most aligned with, that you rush into hoping to feel as if you fit in, it might be more like an angler fish just waiting for you to jump into its jaws.
