invents facts, motives, personal thoughts, personal attitudes, personal conclusions in historical figures to produce a wholely non-factual overall view of the history they portray.

As do all writers of fiction

but they do not believe it is "fiction" it is the truth as they believe it - facts or no facts and unlike most works of fiction it is their clear intent that you believe their claims of "fiction" are just a wink and a nod, and accept that fiction as gospel truth.
