Human Race refers to the Human species.
I think you get my point - beyond the differences in skin color, culture, language, and geographical area - we are ALL the SAME...except for other non-human species like plants and animals - the discussion was to illustrate the common divide that everyone seems to want to bridge - but for certain elected leaders- should that occur - they would power and their standing in certain culture areas of society.
