If we can not make moral decisions as a society, to say "the opinion that minority races are inferior is not one we are willing to tolerate," we stand no chance

If we can not make moral decisions as a society, to say "the opinion that minority races are inferior is not one we are willing to tolerate," we stand no chance to have any meaningful cultural progression. Can you suspend disbelief for a moment? Imagine, hypothetically, that in the world we live in, the one standard deviation difference in IQ between certain races was in fact primarily due to statistical differences in gene frequency. Would it still be morally unacceptable to point this out? Would it still be counter to progress to point this out? If you still think it would be immoral, how can you progress if you misdiagnose reality? I mean if you want to solve the problem, you have to know what causes it. If environment causes the problem, then environmental changes can fix it. If genes cause the problem, then we might have the technology in a few decades that allows parents to level-up their children. In the mean time, if genes are the issue, then universal basic income would be a lot better for disadvantaged then spending money on the school bureaucracy. So if you want to help people, you need to have a truthful view of the problem. Follow-up question. If would be OK to hold the genetic view in world where the genetic hypothesis was actually true, how are we to know which world we actually live in, if people are not allowed to make good faith cases of the evidence and analysis for both viewpoints, without fear of ostracism and career suicide?
