White women have historically been the standard of beauty, white men controlling the media that promotes it, it is in no way shape or form absurd to suggest this having a profound impact on black women, and men. We still see it to this day, look to east asia, they cut their faces, put in the contacts, and dye their hair to be close to white. The less asian you appear, the more you a promoted even in their own controlled spaces. China was upset that an asian women was depicted as "overly asian" in a Mercedes ad. In every country where opposite ends of the spectrum of color shades are present, those closest to white are the stars, look at India, look at Brazil.
See, this is why we need to get away from this free will nonsense, everything makes more sense when you treat people as agents susceptible to influence, from there it becomes so easy to trace the lines to origin, the origin of the problem. An inability to see that the world functions in this manner is simply an admission to a lack of agency, imo. Because think about it, in propaganda, advertisement, and similar fields of influence, at the core of that, is recognition that agents can be heavily influenced. As neuroscience and AI progresses, you people will begin to realize the truth, or at least good luck denying it.
You want 100% agency (free will) with your successes, and you want to shift the blame for your failures.
