I'll give you that, but what I'm trying to convey is that in this film you are going to have many non-black people involved in the production, particularly screen writing, editing, executive producers, etc. We already know based off of history that non-blacks, specifically whites have had and continue to have an overall negative view of black people and in this case African culture. Given that history, there is a chance that some of those ideas could be leaked into the film by non-blacks. I'm not saying that this is as an absolute but you need to be aware.
There is a strong chance that what I described does not happen and it turns out to be a great/positive film but as long as we have racism/white supremacy you should have a healthy suspicion of white people no matter what.
