I have an observation about this debate that I have thought about for the last day or so. Starting with the terms 'white privilege' & 'black disadvantage' as
@Revoltingest suggests, they are each identifying a potential problem. If you ask random internet uses if the term 'white privilege' is a positive or negative idea, many would probably respond by saying it is a negative idea. The same could easily be said about 'black disadvantage'. Perfectly fair conclusions.
Here is the key difference that I tried to explain before but may not have done a very good job. One term creates a villain in the narrative: 'white privilege'. This is my primary protest because the creation of a villain isn't necessary, much less a villain that encompasses as entire race of people. What can you do with this idea? Well, woke users on social media use this as a platform to attack from. When you attack something you want to marginalize and destroy it. This is a dangerous game, it creates negative energy that is predicated on the group in question being white and nothing else.
Now the perspective of 'black disadvantage' is a bit different. It points to a widely accepted and universal (while unfortunate) truth: black individuals are at a disadvantage in certain areas that can cause considerable damage to their livelihood. This is a call to action to
fix something. It is a very difficult and complicated problem. We could use all the help we can get because it is that messy. The BLM movement is having success because they are calling for action to lift a group of people up, not dragging a group of people down. Justice is a flexible concept, but one that always carries a strong meaning. By framing the problem as one group being disadvantaged (instead of vilifying another), it allows justice to occur. Genuine calls for societal progress should always be considered.
