Not sure if you are aware but Chapelle is black

Does the skin color of the person vibrating the air impart some intrinsic quality to it?

The point of the comment above is that the meaning is informed by the listener, you can import all the traumas and neuroses of those around you or you can listen mindfully and limit the impact to whatever is the speaker's intent and capacity to harm you.

In the historical context, where in the US people with white skin had people with black skin as slaves, yes, it obviously does.
