If the differences were negligible, then the behavior and performance of Whites and Blacks would be pretty much the same, like Rottweilers and Shepherds are both herders.

But that's not how it works. We are not the same.

This still doesn't explain the ridiculous comparison of breeding a Rottweiler and a Chiwawa with interracial marriage (breeding/marriage). Breeders would breed any two large dogs regardless of behavior, they would just breed for the personality they want. Furthermore, culture is what influences human behavior and performance, not "breeding". You see, dogs were created by man for specific functions, humans developed naturally to various environments, so it wouldn't make sense to compare them to dogs at all. Our function has consistently been survival.
