The word 'race' should not be used by anyone in any context any longer, because it has been misunderstood, ill-defined and systematically abused over and over. It would be irresponsible to attempt to reappropriate the term into scientific usage.
Apart from that, differences in genetic populations exists just as differences in cultures exist, and I don't think anyone has ever denied that. Researchers need to be aware, though, that there is a bunch of bad human beings out there who will invariably draw the wrong conclusions from such research and advocate policies that are plain evil.
I've never heard of anybody calling someone racist if they said "People with African heritage can be carriers for sickle cell anemia." Likewise, I've never seen anyone called an anti-semite for pointing out that Jewish people can suffer from or be carriers for "founder effect" genetic disorders.
If anything, there's a distinct social justice angle to recognizing minority population health concerns in medicine, so I'm actually kind of surprised things aren't tilting the other way: where the "anti-PC" crowd is angry that researchers aren't focused more on traits that apply to the broader human population, as opposed to the genetics of distinct minorities.
