It is my understanding from following many evopsych types and a bit of reading that there is literally no actual consensus on inherent IQ differences between races, largely because it has not been properly studied (yeah I know Minnesota twin studies blah blah they're not enough). I have not been able to find any credible academic who is actually able to say outright 'yes, there are inherent differences in intelligence between races.' They all say, at most, 'there may be inherent differences in intelligence between races, but we haven't been able to, and may not be able to, properly study this to come to a concrete conclusion.' IQ as heritable is scientific consensus, for sure, but it's not enough to draw racial conclusions.
If somebody wants to convince me of a need for segregation, I'm amenable to cultural or aesthetic arguments, on which there are much better grounds to argue. I think anyone who asserts that races are inherently smarter/dumber is asserting something they wouldn't be able to prove if pushed. Emphasis on inherent is because it is obvious that on average different ethnic groups are smarter than others at any given time, but the question is one of potential.
-> not so deep thoughts
