The subject isn't debatable in polite company because it has been refuted so comprehensively that the only reason to still stick to it is an unwavering dedication to white nationalist ideology.
On this topic, there is no good faith.
Which is obviously not true, but you shouldn't throw out the baby with the bathwater. It's actually an open secret among psychologists that genetics is moderately linked to intelligence and other things like workplace success, though no one that I know will admit even to entertaining the idea, because that would mean career suicide and death threats. But it's not a white supremacist thing. In fact, it can even be seen as the opposite. Race doesn't matter at all as long as you possess those genes for intelligence.
On the Holocaust I'd argue the opposite point -- it was the denial of Jews genetically having a higher IQ that helped lead to the Holocaust. Jews had a level of wealth and achievement disproportionate to their population. So if you don't believe they are smarter and don't believe they have earned it, then the explanation you are left with is that they are tricky and their gains were ill-begotten. And if you read Amy Chua's book World on Fire you'll see this pattern over and over again. A certain ethnic group (Jews, Chinese, etc) does better everywhere they go. But then get demonized by the local population for their overachievement, and pogroms result.
Slavery and genocide have been around forever, since we were chimpanzees really. The Romans were enslaving Greeks and everyone else (who they respected for their intelligence). Slavery was not invented because of belief in racial differences. Slavery was invented because people like taking the sh*t of other people.
The NY Times publishes hundreds of articles a year on racial disparities. If you're going to make it a big issue, then you need to fully explore the reasons for the disparities based on the facts. Otherwise you will get the wrong answers, and the wrong solutions.
How many Jewish populations have been dispersed or annihilated throughout history, and their story lost?
Instead of arguing for scientific racism, would you consider the selection bias inherent in your assumptions.
The snarky "checkmated by FACTS, you emotional liberal!" narrative doesn't work when STUDY after STUDY fails to find any meaningful correlation.
This seems like a far more productive avenue of criticism than "you're a nazi CHECKMATE". This is barely one degree of separation from political conversations like: "Government action? Nice try, STALIN"

That said, I don't think anyone is arguing we should resort to genocide, segregation, eugenics or any of those previous "solutions". I believe people are arguing that unless we can talk candidly about factors for the growing divide, we will never fix anything.
See https://en.wikipedia.org/wiki/The_History_of_White_People where "white" has been expanded and contracted to mean whatever was politically convenient at the time. This is obvious to anyone with even a cursory observation of contemporary American culture. Barack Obama is "black" even though he's equally "white." Keanu Reeves is "white" even though he has an "asian" parent. Argentinians are "hispanic" despite being light skinned and descendent from Italians and Germans, why? Well they speak Spanish. Even the fragility of whiteness illustrate this fact.
This whole "race realism" is the same discredited scientific racism that has persisted for hundreds of years, and is this is the second (and far more virulent) time this has come up in my adult life. The only twist on this very old idea is that now the "smart asian kid" stereotype throws a wrench in the works, when before you you dismiss asians as a bunch of treacherous lazy opium addicts. Now you have to put them in on a near peer to whites, but but discount them as "smart, but not imaginative. Good followers, not leaders." The whole thing obviously is there to simply reinforce existing stereotypes, and reduce humanity to entries in the D&D Monster Manual.
Even in this forum, and this very thread we've got a guy pointing out this out completely with citations, and he's modded down to oblivion because of the actual racists in this forum (themgt, JPKab, wutbrodo, wallace_f, and no doubt others, including those hiding behind throwaway accounts) find it uncomfortable.
So in conclusion, fuck the fascists.
I think you're the one constructing a narrative. From what I'm aware of, there IS a correlation between race and IQ, and it is strong. And it is borne out by study after study. Stronger than the effects of environment and education. Even in the famous Minnesota transracial twin study where adopted black children are raised by wealthy white parents, " the IQs of adopted black children reared by white families did not differ significantly from that of black children raised by their biological parents."
