I'm listening to his interview with Art Bell from a couple of years ago now. I greatly appreciate his work with abductees and documenting the phenominon (showing that something more than widespread psychosis is behind it), but I do think that he was drawn in (or perhaps predisposed towards) the semi-Gaia worship and socialism that our "visitors" tend to advocate. His book
Abduction demonstrated the subtlely malevolent nature of whatever is behind the UFO/abduction scenario, though he himself seems blithely unaware of it.
As another poster said, sad.
