The story behind this is Dax did an open verse challenge on youtube and people submitted their verses to this challenge and Dax picked ones that he felt were the best verses he could put together. So I don't know if any black women submitted a verse or not so its unknown if he just didn't have the option to do so or what. He probably got thousands of submissions that he had to go through that he could piece together a song that flowed. What if no black woman submitted a verse to him? We don't know the full situation behind everything how he picked the people, etc... so I don't think its fair to be upset about not having a black woman in the video. He may have just had to work with what he was given.
