Historians with academic training actually go to great lengths to take bias out of what ultimately ends up as history. It's not a simple case of one version of history vs another. There are things that happen that can be independently verified (especially in modern history). A clip made by some group with an axe to grind should not be given equal validity as proper historical research. They aren't remotely the same thing.It is very difficult to discerne what is true or what us not in history - simply due to the fact that most all of us were not there to know - we can only go on the perspective and opinions of historians and accounts of the people they might include in their view of history - which often opposes other views and opinions - in the end its down to what you or I want to believe - who is most convincing etc - I'd rather be neutral and listen to both sides of the argument/debate - without having to put all my chips on red or black - and it has been said that in wars - the official history is usually written by the victor's and not the vanquished - but then is it really the 'truth?' - we shall forever wonder -
