I saw him speak a couple of years ago. He was indeed pompous and condescending.
I saw him speak in a classic, older almost Anglo-Catholic looking parish. There were maybe 15 or 20 people huddled in a trance within the congregation. Safe to conclude that the women there were on birth control or had had two or three abortions. T.S. Eliot's line about "This is the way the world ends, not with a bang but a whimper" came to mind.
Spong seems to be part of the Phil Donahue/Oprah school of shock jock/lounge lizard pop psychology which holds that if you keep saying the same goofy things over and over again they become true. The fallacy of the "false dichotomy" and "false generalization" are rather integral to Spong's routine. Classic liberal sophistry.
As I spoke with Bishop Spong personally after his sanctimonious and rambling lecture, it struck me how evil-looking and creepy his face and eyes were. If they ever make a remake of Rosemary's Baby or The Omen...
