I think the point of this film is that a lot that has been written about African-Americans about American history has been incorrect and stuff that is true about the community has been left out. Which almost fifty-years later is pretty obvious, but back in 1968 it certainly wasn’t. And that African-Americans themselves probably weren’t very familiar with their history especially the positive aspects of it. And probably weren’t even taught about it. It wasn’t until the 1880s or so that African-Americans were allowed to learn how to read, let alone get an education. Because they were treated by Caucasian-Americans as animals.
The other point being that a lot that has been written and portrayed about the African-American community has not just been racist, but simply false. The Birth of The Nation film from 1918 is an excellent example of that. And then go to the movies starting in the 1930s or so featuring African-Americans were portrayed as servants to Caucasians. Or were seen as criminals that no man would ever dare let their daughters be anywhere near. That fact is left obvious even back then because all Americans were familiar with the movies and TV and all had access to them for the most part.
I think the whole point of African-American History Month is to correct many wrongs that were written about the community in the past. And not portray the African-American community as perfect, because no community is. But to give a more balance look at the community and to point out that this community has given a lot to America from day one and even before we officially became the United States. And to show that even though this community still has a lot of challenges in America, they are by far the most successful African community in the world. That has contributed a lot to America and then some.
