I remember back in 2008, during the whole stock market crash, I got caught up in a Peak Oil/survivalist forum. Back then, it was always the same thing: the big crash is coming! Look at this obscure data point on fish trawlers! It hasn't been this low since 1928! Buy gold! Stock up on food! It's coming!
Of course it never did. I even remember one member saying he was going to invest in the crashed stock market, and all of us shitpiled on him. We were all convinced that this was the end, that investing in the stock market was insanity! ... Of course, he must have made out like a fucking bandit.
That was the first chink in the armor, but then the whole movement started becoming increasingly anti Semitic (surprise!) and casually racist and I noped out of there.
Looking back, I realized that I was simply just sad and angry over a bunch of unrelated, bad crap that had occurred in the previous couple of years, and I latched on to that movement in order to feel smarter and to feel that I would have one leg up over those who had wronged me.
So in a way, I understand their frame of mind, and have hope they are not all completely lost.
