Though maybe classification schemes are outdated, I'm still highly fascinated in physical anthropology, and physical differences. I would still like to see more work along the lines of Cavalli Sforza's, who seemed to be genuinely fascinated by population structure while recognizing that strict classification is "futile." That an interest in differences can create social division is a sad consequence, I think. I would have no intention on trying to separate peoples with science - my interest is purely physical and genetic, but I understand how this type of data could be used for more than that (ahem - racism). Likewise In a humanist, egalitarian society, I think our focus on promoting equality will outweigh scientific quest for "truth," even for curiosity's sake. I can't say I can blame a person for having a problem with it, not when human well-being is the top priority. Perhaps one alternative to avoid overt scientific racism is to look at individual physical traits separately, so that it isn't tied to racial hierarchy, but simultaneously acknowledges the physical differences among humans which are undeniable?
