First thing is, I am not an American. I am a White Welsh person. That said, there is significant systemic inequality in western countries, that is often racially biased. This is what is meant by "intersectionality". The other response talks in terms of "class warfare" and it is important to note that the whole reason Intersectionality arose as a concept was because "upholding women" often meant "upholding white women", and "upholding lower class workers" often led to measures that did not consider people of colour, and therefore led to them being more disadvantaged. You cannot view oppression purely in terms of class, when you do, voices are unheard and lost. Because of the cultural split, enforced by said systemic inequality, there is a cultural difference. It would be foolish and ignorant to ignore that difference and claim that it doesn't exist. Indeed, "Colour Blindness" as you are proposing, has been outed as racist ideology for over half a century (Jane Elliot explains this rather well). By ignoring the fact that people have different skin tone, and have been disadvantaged by it, you are choosing to ignore their very existence. If the entire human race were "homogenized" there would be much of value that is lost. Likewise, when we talk in terms of "white people" and "people of colour", we are simply recognizing and acknowledging the split that comes from that disadvantage that still exists -- in terms of the original argument, we are recognizing that this specific encoding of sound information is likely biased to encode white culture, white art, better. That is a difference that should be corrected, and to correct it we need to acknowledge it first. In summary, I'm simply following the terminology given to me by people of colour, who often talk in these terms. The best I can do is follow their example and speak out in the manner that they have taught, or (better still) promote their voices on these matters.
