Since we have mapped the full genomes of H. Neanderthalensis and H. Sapiens and found that approximately 70% of extinct Neanderthal DNA is now distributed across the extant Sapiens population any notable differences should logically be based upon DNA. I.E.: based on inherent chemical differences which are meaningless except for untoward disease processes. Sadly, that's not how societies are. Discrimination on skin color, i.e.: biological sun screen, and culture, e.g.: religion, food, clothing, language, whatever, seems stupidly illogical in the extreme; dislike notwithstanding. IMO. Since Neanderthals and Sapiens interbred , seemingly with abandon, we are all the same at the species level
