Based on my recent studies in sociology and social psychology my answer to the question of whether the historical events, rules and laws presented in the videos impact our society today, is a definite yes. Unfortunately. Misfortune and social status have been proved to be over-generational (meaning that we _tend_ to inherit the social status of our parents/families for a number of reasons) and additionally our thinking is rooted in our socially constructed culture and the language we use. Trying to support those who are oppressed, discriminated against and have fewer chances to succeed is one way to go, and it is important, but it is not enough. Any events of the past, whether from last week or from two hundred years ago can leave their marks in our policies, our language, our culture and the way we think - even if we don't want to think that way. (I don't want to automatically feel more threatened if I see a black man walking on a dark alley rather than a white man, but this might still happen because of the accumulated cultural "knowledge" I've gained from watching films etc.) However, this also means that there is something we, together, can do about this. We can and we should fight against discrimination and racism, and it will only be possible, if we notice the big and small ways in which we all, whether we want it or not, are used to thinking in color. Race is a social construct, thus reducing racial injustice requires a new kind of thinking, a new kind of social construct.
(SIDENOTE: I'm a white European living in Northern Europe. As part of my basic education and my university studies about languages and cultures (in Europe) I've come across quite a lot of information concerning terrible historic and current events happening all over the world, where racism is often weaponized to reach other goals . I've been concerned about the rise of populist right wing politics, and I've seen the extremely saddening stories of individual black Americans being abused. Because of my personal interest towards black American culture I've read a lot about the related history and I've had the honor to hear black Americans in the field share their stories. Still, there was a lot of information in the videos that I didn't know. This, in my opinion, shows how much more openness and sharing is required. My university studies were not specifically about race or social injustice, nor about America, but I'm still a university educated person, who is very culturally wired and concerned about social inequality in general. If so much of this information was new to me, even though unfortunately not very surprising, I can only imagine how much of it is unknown to the majority, who might not be specifically interested in these topics.)
