Notice how mainly all the people saying this movie is doc is terrible dont really engage with the movie, they're largely blame shifting racism and slavery to say that it's equally shared blame by black people and white people. Or bringing up slave trading in Africa by Africans or the 0.9% of slave owners in the US who were black as though the laws were written to protect their slave owning interest instead of the remaining 99.1% who were white. Any time history is presented that makes White Americans feel bad they have to call it lies or half truths or divisive. Don't play into their hands. These are uncomfortable truths about how this country treated and continues to treat non whites and the backlash comes from how successfully invisible these truths have been made to the White people in the comments acting out. They don't see it, so it must be a lie somehow.
I grew up learning most of this so i already knew about most of this with the exception of the work of Phyllis Wheatley and Ida B Wells. What's sad is that this is pretty basic history but I give it five stars because of the importance of knowing these bits of history, but apparently with the comments here this basic knowledge is forgone in lieu of a sanitized mythology of how America was built. The acts shown in the doc show the white rage of the past and how it continues to work into the present day to dehumanize, other, rob others of the freedoms whites take as for granted.
