Race is extremely difficult to control for opposed to income, employment, education, etc. It's difficult to understand from a european racial perspective, but it's like stuffing everyone from the mediterranean to scandinavia into the same race. People who are otherwise genetically disparate share skin color. This is extremely evident in Africa proper but is also evident in e.g. the american "African American" ethnicity. TL;DR unless you're trying to correlate with a specific gene, you're gonna be called racist for trying to correlate skin color to anything. Race in general is a word that is difficult to use correctly in an argument unless you're shooting down someone else's argument. It is virtually meaningless outside of how people extrapolate phenotypes to ethnic identification.
