Greg Laden is one of those people who want to abolish use of the word "race" to define genetic subpopulations. He claims that there is no such thing in humans (or in other species). But even if it were biologically correct we shouldn't use the word because is has been misused by non-scientists.
Here's an example of his reasoning from The Scientific, Political, Social, and Pedagogical Context for the claim that "Race does not exist.".
The race concept has been very successful in its many nefarious applications, but this is not what I wish to speak about here. Rather, I want to acknowledge that a concept that divides humans into a particular set of groups in a useful way might be, well, useful and not such a bad thing. The fact that medical researchers use race to divide subjects, and find differences between races, and that these differences are important to know about, is important, even if it does not validate the races. What it means is that an unworkable race concept works sometimes, even if the races themselves don't exist. Nonetheless, it is reasonable to acknowledge that even though races don't really exist and many, if not most, applications of the race concept are obnoxious, it may be that its use is not entirely inappropriate all the time.Greg and I have been over this ground before. It think it's silly to pretend that races don't exist. That's carrying the anti-racist agenda too far.
I will argue, however, that the down side of the use of race requires its abolition among scientists. Since race is usually not a biologically useful concept for humans (or many other species), and is never a truly valid concept, it is difficult to justify its use given the negative political and social consequences it carries.
