Thing is Matthew, you and I are about the same age and I've heard this "end of the world as we know it" line for 35 years. It has always been "just right around the corner". Lots of the people I remember saying it are now dead, or as close to it as makes no difference.
Remember the 1970s and 1980s? Protect and Survive? I remember growing up with the threat of nuclear war ever present. I remember Trads spinning whatever geo-political problems were going on at the time into some societal collapse.
I remember Y2K and the Millenium Bug. Some of the younger people here don't but I can remember SSPX priests and Williamson himself suggesting that Y2K might be TEOTWAWKI. Then 911 and let's face it that was a pretty shocking and surprising event. And then the Boxing Day Tsunami, 1/4 million people suddenly dead. Then the 2007 banking collapse which, let's be honest, looked pretty much like the end of the capitalist funny money system. And yet here we all are 7 years later. The economy in the doldrums perhaps but nothing like the disaster scenario predicted. The "derivatives time bomb" still unexploded.
There will be a third world war, of that I am sure. One simply has to look at history to see that wars come and go and are a part of human politics. But when, who knows? Will it kill everyone? Who knows? Will it kill first worlders or third worlders? Who knows?
Since you are pitching these disaster scenarios to humans, "right around the corner" applies to a human lifetime, not that of a giant tortoise or a Californian Redwood tree. Do you accept that along with a warning comes a moral responsibility to review those warnings and temper them with a mental balance and some clarity that there is far more we don't know about what might happen than what we do know. And we have absolutely no clue as to the timing, as a search of all TEOTWAWKI posts in the last 15 years on the internet clearly demonstrates. To speak of things being "right around the corner" therefore is misleading hyperbole. You simply don't know that.
Would you accept that most people considering these potential disaster scenarios are not going to be unaffected in their decision-making. Would you accept that someone might put of marriage, taking out a mortgage, making a long term investment in say medical school or law school which will only pay back after 6-10 years if they think there is a reasonably high chance of TEOTWAWKI being "around the corner"?
