How history changes over time is what makes studying history so fascinating, discovering that "facts" you knew to be true *for decades* are maybe not so true.
Primary sources are valued by historians for very valid reasons. Its not that 'facts' change, but that new facts emerge from newly discovered primary sources.
Facts do not change in certain cases so much as interpretations of those facts change - which can be a good thing, when informed by primary sources.
For example, we long thought that the serfs during the Middle Ages were a fairly static lot, 'chained' to their lord's land for life, pretty much slaves. While this may have been in the case in certain locations - e.g. Russia - scholarly study of primary sources relating to mercantile trading have revealed that there was a great deal of movement of serfs from one landholding to another, and that serfs even succeeded in becoming landholders themselves. This alteration in our view of serfdom has come about not with a different interpretation of the facts that we knew, but more facts generated by the study of primary sources.
I'm not, wouldn't occur to me to be so.
Certainly not 'afraid' of these two gentleman's spin (because what they are doing is so obvious) - only concerned that so many cannot identify when they are being taken for a ride - as I think many are who are subscribing to their site. Or at the very least, some dots are missing in the connect-the-dots game being played. Look a little closer.
when you encouter deviations from the Standard American Narrative.
I honestly don't know what the standard American narrative is. Take a gander at historians' work - they disagree to a compelling degree. Unless you are referring to the Texas-authorised history textbooks for schools? Is that what you mean?
Have fun disproving them.
I leave it to the discerning ear to do that. The problems with their spin is obvious - and I thank you for showing them here. Makes a lot of things that are currently going forward under the guise of 'facts' in our current political climate understandable - if this is the kind of stuff being peddled and believed.
Start with a deviation that is easy to disprove, like the Faked Moon Landings. Then move on to more ambigious deviations like whether Pearl Harbor was "allowed to happen". Then look at really fun stuff like Yamashita's Gold, Prescott Bush & the Nazis, or hitman Malcolm Wallace.
The sad part about all this is that we have, in fact, indeed, lost our investigative newspapers across the country. (Conspiracy there, if ever there was one).
Read history - good history - understand human nature - and none of the above will have ever been a 'surprise' to you.
Do you know why the Faked Moon Landings nonsense began? Bethcha you don't.
