I read in one book where the author stated that conspiracy theories are developed by persons with some kind of a disorder in which they can not accept reality or that things simply happen as they do.
Have you ever sat in a pub or in regular company and you and your friends listen to a Billy liar type.
Lol, that's you. The multimillionaire North Korean dissident who has 17 patents, drives a Bugatti and is building a working model of an ice dome covered earth.
You need to prove all of what you've said or it's you that's the Billy liar. 
You really think that lying about army stories or travelling salesman adventures is somehow even relevant to a discussion about the systematic murder of 6 million innocent people?
As to whether it's part of the flat earth conspiracy mantra or not, here's what some of the creepier people at IFERS are saying.
As for the possibility that the whole movement could be labelled as jew hating holocaust deniers, that might be actually a good point, but seriously, I think that holocaust deniers get generally more credit than flat earthers, so it could actually be beneficial
Either way what can you do? Keep quiet in fear of being labelled? Than we should drop the flat earth business in the first place.
Being a conspiracy theorist for years and looking at the over whelming evidence of the Zionist Masonic influence on this world, it still amazes me how people can say it's Jesuits or bankers or the elite that control the world. To understand flat earth you kinda have to be deep down the rabbit hole. There's no flat earther that believes terrorist did 9/11. You kinda got to well be versed in conspiracys be a flat earther imo.
This is a long long way from Billy Liar telling stories at the pub.
I'm not accepting nor denying it, so seeing as you appear to know all about it, by the way you're using emotion to argue, I'll ask you a few questions.
1. Over what period were 6 million killed?
2. How many camps were used for this?
3. Where were they buried?
There's a few questions. This is all I can do other than to blindly accept the history without knowing much about it, so seeing as you started the topic, maybe you can answer me and help me come to a logical conclusion.
Do your own research, I'm not your unpaid research assistant. My logical conclusion is that a high proportion of conspiracy nutters are racist anti semites. It pervades the 911 movement as deeply as it seems to pervade the flat earth movement.
And use your brains Geoff, you said yourself there are only 300 FEers so of 7 billion people odds are there is a high number of RE wacko's.
I am totally over hearing about FEers being conspiracy theorists, I personally think the problem is the RE wack jobs starting these theories. Give it a rest will you, you are like a scratched record.
I'm not Geoff, but you already know that, and so I'll take that as a wind-up.
You aren't a flat earther, so you might have a fresh perspective, in order for the flat earth idea to be correct, there has to be a massive conspiracy to hide the fact, and fake everything from GPS to Satellite TV and space programs, South Pole, Flight times etc.. etc.. and on and on forever it seems.
So are you suggesting that there are flat earthers who DON'T believe in the conspiracy?
