OK, I can see that. It’s a motion detector, but that relies on an “electric eye” a beam that is shot out and when something comes in front and reflects it back, the soap comes out. I can see how darker skin could fail to trigger it as easily as dark absorbs light better, or reflects less light back. However as the user admits, those of color have areas of their body that are NOT sun darkened, right there on the item to be washed, so I would advice remembering that when you start going with cancel culture, eventually EVERYTHING must be canceled.
Why can’t they just hire white people as restroom attendants? /s /s /s
