Yes.
I have spent 11 years and more collecting books and reading other sources that reveal the origins, effects, and afterward of American slavery. Also how the white and Native American slavery of the American colonial period played out. There is a lot of complexity in the business and the brutal personal and social effects of slavery.
Reading the enduring effects in convict leasing, debt peonage, Jim Crow laws and the faultering weakness of reconstruction in behalf of former slaves as well as the pogroms of black communities into the 1900's,you see how ignorant the public is--including many in black communities--of the DNA of slavery on U.S. society. Black and white.
I agree with LisaObeesa, all should see this film. If you are not well informed on the complicated befores and afters of black slavery, before speaking one way or the other on race issues in our communities---- see this film.
Yes, there was a war that officially freed blacks. But the slaveholders and those who felt/feel that blacks are fundamentally inferior and (choke, gag) benefited from forced labor i.e. free food and housing, they didn't have a change of heart just because the South was defeated in 1865. They raised sons and daughters, who raised sons and daughters. They were the landholders, business men and community leaders who shaped policy up to this day. The changes in civil rights since slavery were meager and were on paper but there were black men and women 100 years later who died in the south for trying to live according to those laws.
Racism has a long half life.
