Whyme No I am not; and of course I am aware history can be slanted either by commission or omission. There has for example, been a lot of heart-searching in my country about history from the viewpoint of our former Empire subjects, as well as Britain's own side of it.
Hollywood obviously is not, and to be fair does not claim to be, a historical research organisation even about its own nation's history.
I do not know what modern British school history syllabi contain; but I think we did cover the development of the USA in my own time at school, and that would have included the Independence, 1812 and Civil, Wars. That was half a century ago, though, so please accept my memory may be at fault there! After all, I did drop History and French from my set of the formal end-of-school exams; and I have not studied either in a formal way since.
Genuine history should of course be accurate, objective and fair. Otherwise it becomes propaganda; but that very fairness can sometimes be very uncomfortable for either "side" in anything contentious.
