It is definitely lazy and superficial, but it does not necessarily make for a terrible indicator. We are much more receptive to color than small shape variation

It is definitely lazy and superficial, but it does not necessarily make for a terrible indicator. We are much more receptive to color than small shape variation, by removing the former you are preventing (or at the very least mitigating) comparison and the creation of stereotypes. Now I am not from the US so I won't comment about history, and I can fully believe that there is some link between being a white nationalist and believing one "race" to be superior to the others, but I do not believe that this is a reason enough to disqualify the idea.
