And it should be known that there ain't no way to hide those lyin' eyes. (My favorite of theirs was always this.)

I will say these pseudoarchaeologists have a lot of audacity.  I suppose it has something to do with their absolute certitude and megalomania.

Looking into the World Ice Theory, I was treated to another wonderful line by Hörbiger: "Either you believe in me and learn, or you will be treated as the enemy."
  

Are you going to believe me or those lying eyes?

Cosmic Ice Theory—Science, Fiction and the Public, 1894–1945

A Song of Ice and Fire

Eric Kurlander's book looks interesting.  It's been out long enough to be available in a cheap used paperback.  

As Giselle in the video points out, this was typical pseudo-science.  It presented itself as scientific theory but it did not resort to demonstrating that truth by recourse to the evidence but by allying itself with powerful people who could use their influence to force others to their point of view. 

One disturbing aspect is that current Conspiracy Theorists, who would be horrified and indignant to be associated with Nazism, still retain some frankly, racist attitudes.  The too common idea that the ancients were simply too stupid, too "inferior" to be able to accomplish such feats of construction as the Pyramids of Gizeh or the Heads on Easter island without help from "advanced" civilizations.  It hardly needs explaining how this viewpoint supports a colonialist prejudice that observes all those primitives out there who badly need us to come save them from themselves (and from their natural resources which only we know best how to exploit).

So many things I could comment on but will limit myself to just a few.

That notion the Nazis had that the Aryans were responsible for every single major civilization seems to be an idea that modern pseudoarchaeological theories hold as well.  The local people back then couldn't have built something so advanced.

She is definitely right that misinformation is everywhere.

My favorite line was by the Austrian proponent of the World Ice Theory: "Calculations can only lead you astray." 

Nodet and Taylor (supported, among others, by statistical research by G.J. Goldberg) note a striking structural and lexicon similarity between the Flavian Testimonium and the Gospel account of the disciples on their way to Emmaus (Luke 24:19-24). In their theory, Josephus did not copy the Gospel of Luke, nor did Christians add fragments to Josephus based on it. Both texts draw from a common, lost Aramaic or Greek Judeo-Christian source (the so-called proto-Gospel). The Testimonium acts here as an "external witness" to the existence of a very early, uniform tradition about Jesus, which circulated in Palestine even before the Gospels were written.
Josephus concludes his passage with the observation that the "tribe of Christians" (Greek: phylon) existed to his day. For Taylor and Nodet, this provides sociological confirmation of their main thesis: Christianity in the 90s of the 1st century (when Josephus was writing) had ceased to be merely an internal, Palestinian baptismal faction. It had become a distinct, autonomous social structure within the Greco-Roman world, while retaining the memory of its specific roots.
This theory is sometimes referred to in the Anglo-Saxon and Frankish worlds as Nodet's hypothesis, and although it is considered an exceptionally brilliant literary analysis, it remains largely a minority hypothesis.
Well, yes...
A small request. If anyone finds a common lost Greek or Aramaic source, please let me know ASAP. Without it, the continuity of the Palestinian baptismal faction with NT Christianity is merely wishful thinking. This is important because the NT authors were perfectly happy with the LXX and Josephus. No extra hypothetical sources needed.

Everything is filtered through a particular lens and shaped into the mold they've already formed.

I first heard about this stuff in the book Morning of the Magicians.

Reality is often stranger than fiction.

Be gone with you, you shod and shady senators

Give out the good, leave out the bad evil cries

I challenge the mighty titan and his troubadours

And with a smile

I'll take you to the seven seas of Rhye

"Unlike other popular conspiracy theories New Chronology is not intrinsically antisemitic, but it contains claims that may be unwelcome by Jewish communities, like that the Old Testament is newer than the New Testament, placing Jerusalem in Constantinople and projecting stereotypes of Jews by proposing that Jews originate from bankers in the Russian Horde that adopted the religion of Judaism, itself a derivative of Christianity and not the other way round."

A few years ago there was a conspiracy theory making the rounds that insisted that the Roman Empire never actually existed. I wonder if that one was in any way related to the The New Chronology?

Could very well be. 

If I understand them correctly, there was no Roman Empire, and neither was there a Josephus to write about a Jewish uprising that never occurred.

As for purpleness...

As I said I love a good crank.  Most conspiracy theories don't rise to the level of True Crankiness.   Growing up I went through a JFK assassination phase, and a UFO phase.  But I have a quality that has served me in good stead over the years. I practice Total Immersion.   When I get interested in a subject I read everything.  Consequently it doesn't matter what my entry point is because eventually I get to the Good Stuff. 

The True Crank must be possessed of a singular fixation that dominates his or her entire way of seeing the world, combined with a passion to inform the world of their insights. All fire hydrants must be painted purple.  Not content with expressing such a claim they must also produce a metaphysic of purpleness.  The best cranks tend to be creatively talented in some way so out of their fixation comes not just philosophy but some aesthetic creation to illustrate their perceptions of reality.  While their fixation may prove self-destructive or a baleful influence on fellow travelers, it must not itself advocate destruction or be possessed of hatefulness. 

Our world would be poorer without such people.
