I submit that the idea of 'race' is based solely on bad science and doesn't have any real meaning such that it can be related to anything else.

Nevertheless, the word "race" remains a useful shorthand for "populations differentiated genetically by geographic location" or what have you. If you don't think there are genetic differences between, say, Northern Europeans and Sub-Saharan Africans, you are literally blind. They obviously belong to groups that evolved in different directions. That does not have to include intelligence, but it's not reasonable to refuse to consider a hypothesis just because you find it repugnant.
