I don't see what's wrong with suggesting genes are causing the gap. I'm not "dogwhistling" anything, this is the most powerfully supported scientific explanation. Science denialism seems to be extremely common on this forum. Genes definitely cause other gaps like sports gaps (or do you seriously believe that is because of racism in favor of blacks?) and are known to play a huge role in ability. Even if races have equal ability, do you seriously believe the extreme selection process for elite immigration won't affect outcomes?
