I can't say anything about this concrete case, but I think especially from an anti-racist and anti-sexist standpoint, one should thoroughly and ruthlessly perform research into differences, as that is the only way to falsify racist and sexist ideas. But if one is not convinced of anti-racism in the first place, and only conforms out of social pressure... then I can see why one would be afraid of such research. But what if research does find out meaningful differences? It's all a matter of how we look at it. We all agree that they are differences between different families. In one family people tend to be tall, in another they have musical talent, and so on. Its undeniable that there is some influence from genetics in our lives; it mostly becomes problematic if we think of it in terms of races, gender, instead of "my genetics, my parents, my ancestors". When it becomes essentialized, and puts people into boxes where it becomes a destiny (X people are like Y). I think in a saner world, we would want to know as much about our genetics and out biological potential as we could - alas, we are not in a sane world yet.
