Ty, I'm reminded of the finding that people who are diagnosed with cancer, or lose a limb, or suffer some other serious trauma, often remark after the fact that they feel they are *better off* than they were before. It isn't particularly rational, but it is very human. We are capable of adjusting to crazy circumstances, and then carrying on with our lives.
I think he was right in calling the mass die-off, but that the way people clustered together in convenient SCA-branded bands after that was a stretch. That said, I think the number of fairly reasonable calls he makes outnumber the bad ones (although some particularly egregious ones, I think, are the rampant cannibalism, the near-instantaneous rise of cottage industries like brewing and smithing, or the coincidental growth of Wicca.)
If I had my druthers, I would spend a lot more time with the self-sufficient, rapidly militarizing monks than with the irritatingly American survivalists and their random British friends, but I suppose that's just him being considerate of his primary audience (lovers of military fiction and fantasy.)
edit: And if I could excise every single reference to the lord of the rings, I would do it in a heartbeat. In fact, I might just do that to all of my copies...
