There is a weird documentary called Aether made by a channel called the blue the producer is a women called marcia ramalho. The producer basically bases it's bs on the Tartaria conspiracy theory. Can anyone dissect that garbage and prove the bs wrong?
u/EnclavedMicrostate provides an explanation of some key terms and why the whole idea of a "tartarian" state is nonsense.
The same user talks about the conspiracy theory in a podcast here!
It seems in the answer they are responding to the idea of there existing a centralized tatar state around the 15th-18th centuries. This is based on a pretty egregious misunderstanding of sources but seems, on the surface, innocent enough. THE tartaria conspiracy theory though, that this empire covered the earth and was swept away in a mud flood maybe 200 years ago or less is....well all conspiracy theories are to a greater or lesser degree nonsense, and this one is greater.
The idea of a moon landing hoax, for example, is aggravating and its adherents frustrating BUT at least there's a plausible motive (winning the space race) and the mechanism of the conspiracy theory at least exists (faked video). However, it's harmful because it is an accusation against still living people and extant organizations. Specific people, like Buzz Aldrin (look up him punching someone calling him a liar for some catharsis).
I would put the Tartaria stuff in the same boat as maybe flat earth - there is no evidence for it and literally all evidence, ever, against it. Shoot, I probably at least get the ancient aliens people a little bit better (I have a good friend, with a master's degree in aerospace engineering, who dabbled in it a little courtesy of the damned history channel). They have the courtesy to set their conspiracy so long ago that they can at least claim ignorance there.
I honestly think the best thing is to not engage. My toddler misbehaves for attention, and I feel like this type of thing is a sort of intellectual misbehaving. The advice is to not give the toddler feedback - positive or negative - and I think the same applies here. The people who believe it in part LIKE the idea of the intellectual "elite" (i.e. anyone with an elementary school education) lashing out in anger and it just encourages and fuels them.
Edit: the podcast also mentions that some unknown quantity of people doing this are, and I believe this is the technical scientific term, "shitposters." Their behavior is a bit more literally like my toddler: post outrageous stuff (in my day we'd add the technical qualifier "for the lulz") and chuckle at the outrage. Another reason not to engage. They like it because it's their goal, and the (hopefully smaller) portion of true believers like it because they can twist it to validate the conspiracy. You can't win because they've manufactured a scenario where any action is more proof.
Edit: Heaven help me I've gone and visited the tartaria subreddit and.... honestly my impression is most of the top posts are of the "goofing around" kind who don't actually believe this. I almost get a role playing vibe. That's not to say people don't really believe it but I'm skeptical it's a significantly big movement.
