Your latest insightful comment on "Alipang" made me think of "The Pilgrim's Regress," which is one of C.S. Lewis' least-read books because it's harder to understand than most of them, yet which does contain valuable illustrations among its metaphorical episodes. One chapter has to do with ultra-liberal churches pretending that their trendy fads are nourishing them spiritually, while actually remaining in need of the nourishment of traditional Christianity.
I am still pondering how far to go in showing that the Enclave exiles represent the preservation of old and valuable things. I might go so far as to depict the Diversity States losing its whole infrastructure, whereupon the exiles are the only ones in the nation with skills to keep some of the other people alive.
