People that don't want to have their worldview changed by having to come to terms with immutable differences between population groups and the consequences of those varying behavioural predispositions living under the same set of societal codes.

I think there's a lot of nuance here. there is more difference within populations than between populations, so the correct thing to do is still err on the side of treating individuals individually. that is: genetic profiling doesn't pay off. other forms of profiling are probably way more efficacious (like by belief system. ahem)
This is like saying "there is more difference within cars than there is between cars and trucks"
