I didn't know claiming a genetic component in explaining differences in racial averages for IQ is scientific racism.
I would argue that racial genetics science itself is not racist, but it can be executed in bad faith, and has a high potential for misuse.
One can ask the following in good faith, absent of racism:
1) Is there a genetic component to intelligence
2) Is it heritable?
3) Are there differences in these genetics across groups?
What policy conclusions one draws from any conclusive findings is the controversial part.
