I'm no expert on haplogroups either, but cursory googling seems to indicate they are far more numerous and nuanced than the late victorian, scientific-racism derived classifications used today - i.e.: black, white, asian etc.

But we don't need to be specialists in population genetics to observe that human cultures interbreed. We can't reliably correlate visible biomarkers with genetic origin, especially in contemporary multicultural societies or any of the places where numerous land invasions over thousands of years have ensured continual group mixing. For example Indian subcontinent, Afghanistan, Mongolian steppe etc. My nephew is half 'Irish', half 'Indian'. But what does that mean exactly? His ancestry is likely to contain contributions from hundreds of subgroups and linguistic populations across South East India, as well as Ireland and the UK more broadly. Visibly he looks 'Indian', but what does that mean for a determinant of race?

These concepts were engineered in the colonial era. Only the names have changed. In college my friends and I picked up a cut price set of colonial era British encyclopedia. They had lots to say on racial groups, with detailed descriptions of the personality types, intelligence and appearance of groups like 'negroids' and 'hibernians'. Of course none of this was based on what we'd today term scientific reasoning or measurement - and yet the conclusions and stereotypes persist in our culture. Irrespective of powerful counterexamples demonstrating that culture and economics determine an enormous amount of educational and attainment potential. e.g.: Nigerian American economic success [1], the explosive boom and continual exceptional economic performance of Ireland [2], or the absurd difference in educational outcomes of countries which are ethnically homogenous but politically divided - e.g.: North and South Korea, Haiti and Dominican Republic etc.

Remember interindividual differences radically outpace intergroup differences. Which is not to suggest that highly homogenous ethnic groups (e.g.: askinazi jews, or certain West African populations) can't have significant differences in athletic ability. But such differences are on population levels much smaller than observable 'races' per say.
