Dan Martins writes about the division of Stockton, California between the two competing Anglican dioceses in Two Tales of a City.
I would particularly call attention to his response to Sarah. One of the conceits of the puritan faction is that ECUSA is (except for a few faithful parishes and dioceses) composed of licentious Unitarians. There are parishes like that, of course, and dioceses where the bishop and his staff are like that. But most of the sexually-obsessed liberals aren't Unitarians, and in amongst the liberal command posts and conservative outposts in those dioceses, there are a lots of parishes where the rector doesn't constantly make coded sermons on inclusiveness, and where those who have any notion about the Unitarians make jokes about how the UUs pray "to who it may concern."
One of the not-too-well-concealed issues in the current program of departures is how it's being a bit of an evangelical triumph. While I'm still wondering how the Anglo-Catholics fit into this, it seems increasingly the case that the GAFCONites etc. don't particularly care that they keep approaching the issue of separation in a manner which is repugnant to the middle-of-the-road, if not bordering on slander. The result of the hyperbole about the character of the church is that the people in the middle don't believe the GFACONite/ACMA/etc. crowd, and they do believe the liberal hierarchy's accusations about the schismatic intent of their opponents because the accusations, well, appear to be true. The one group that the "evangelicals" don't really want to evangelize effectively are their own fellow churchmen.
