Answer:
It is true according to revisionist historians, who don't uphold orthodox interpretations.

Historians can't be orthodox in their interpretations, because here a point of view is based on external evidence, which are other's people perspective.
For example, you are a historian. So, right now you are studying some theme, but the important events are in the past, and this obligate you to recover information interviewing the old people.
