I think some people are confusing "Long Term Survival" with what I guess should be called "Epochal Adaptation."
If what happened in New Orleans could be compared to Pompeii, it should be remembered that the Roman Empire continued to exist after Pompeii for almost four centuries. People who survived Pompeii endured Long Term Survival. Those who endured the fall of the Roman Empire Adapted to a new Epoch.
Long Term Survival almost certainly involves a dialogue about ethics, but probably not ideology. Epochal Adaptation invariably compels ideological discussions and conflicts.
I think that's where the difference lies, and time is often not a factor. It's sort of like pornography: you know it when you see it. Sort of like the difference between evacuation and migration.
I don't see the need for a separate forum, so long as LTS issues (as nebulously defined above) are discussed in a functional and ethical context. Anything else should be left to the Hippie Homesteaders and Bunker Bubbas.
My two cents, after a long absence from posting.
