Yes. The claim is usually that black people (or whatever alleged inferior race) are, on average, genetically predisposed to being inferior. Usually the claim has to do with intelligence and/or a predisposition for criminality. Lets accept those alleged facts as true for purposes of discussing the policy implications. Now combine those alleged facts with the undisputed facts - the observed racial disparities and you then have the question - To what extent are the observed racial disparities caused by innate inferiority as opposed to adverse racial discrimination? It would be reasonable to assume that both factors were contributing. Yet, even if there is racial correlation to a predisposition to some innate inferiority, racial discrimination would still (in most cases) be an injustice that should be mitigated through policy.
It seems that you don't actually think race realism is false, but that you believe it's true and are afraid of where the implications might lead. You wish it wasn't true. I also wish it wasn't true, but the facts seem overwhelming to me that there are differences in group abilities. Unless you have an alternative explanation for why West Africans are so incredibly good at sprinting. Why tiny Jamaica does better at this sport than China. I see no reason to assume that adaptation spared the brain.
"Inferiority" is your descriptor, not mine. My best friend is smarter than I am, by any reasonable metric. But I don't feel "inferior" to him. On that specific facet, I guess. But I'm defined as a person by so much more than just intelligence. Kindness, wisdom, courage, honesty etc. are all virtues besides simply raw intelligence.
So, what's wrong with racial discrimination in the first place? Lets say that you're a sole proprietor and you desire intelligent workers without criminal propensity. To that end, you implement a racially discriminatory policy, that you will not hire black people. What's wrong with it? It's your business. It's your money. Perhaps you should be able to do what you want with your property, at least that's what the libertarians say. Nonetheless, even supposing it is your right, that does not make it right - And it is still wrong, even assuming the fact that being black is correlated with low intelligence and criminal propensity. And why is it wrong? It's wrong because people are worthy of better treatment than products where we may shop according to brand without any further investigation. With power comes responsibility, and it's wrong because it's an unnecessary unfairness that can be easily avoided by minimal inquiry on the employer's part in to the prospective employee's background. For example, filtering out the stupid and criminally inclined may be done simply by adequately interviewing prospective employees and conducting criminal background checks, etc.
On the contrary, it is the status quo that makes discrimination economically rational. There are those studies about how resumes with "black sounding" names get less call backs than "white sounding names." I've long thought this had more to do with class than race (and there is good evidence to suggest that) but someone pointed out to me the other day that this discrimination actually makes sense in light of affirmative action policies. The odds are that a black guy and an asian guy with Harvard on their resume are not the same. The asian man almost certainly had to work significantly harder to get where he is, and possesses more intelligence and skill. While black people get a 230 point bonus to their SAT scores (more than a standard deviation!) asian people are penalized:

In a world where the elites accept race realism and understand that elite universities can be expected to have an overrepresentation of asian people and an underrpresentation of black people, everyone would also know that the black people who made it there got there through merit. This doesn't stop at elite universities btw but continues down the university chain and well into career paths.
In any case, the point I'm trying to get across is that public policy should favor fairness, which would generally be against racial discrimination despite the fact that there may be some innate inferiority that is correlated with race.
Let's talk about what's unfair. As a white person, I think it's unfair that my group is constantly blamed for holding black people down. If there is a disparity between white and black people on any metric, it's our fault for being racist and implementing racist policies. I think it's unfair that if you search "white people" or "white men" on any social media website all you get is a slew of racism.
Yet deep down, almost everyone knows that some degree of racial realism is true. The cognitive dissonance is quite literally tearing this country apart. I don't think public figures talking about race realism is ever going to be a good idea, it's the type of knowledge that does have the potential to be truly toxic. But for God's sake, shut up about race and stop attributing all differences to racism.
I don't think most racial discrimination is even like that. It comes across more as some in-group favoritism thing to me rather than a racial hatred thing. Blacks especially are seen as different. Perhaps it is because they look the most different, and perhaps it is because the American population is bombarded with media indicating that blacks are a different and unique people, separate from the rest of the population. It's unfortunate that so much of that media was made with good intentions. Perhaps if the media presented blacks like Geordi La Forge rather than Will Smith there would be substantially less racial discrimination.
This is the inevitable consequence of living in a multi cultural/multi racial society. Empirically everyone (except for mentally ill white white liberals) has an in-group preference. At some point you have to play the cards you're dealt and acknowledge human nature for what it is. I don't understand what's so hard about that. There are always going to be stereotypes, true and false, positive and negative, and it is completely impossible to divorce yourself from this, but it’s important to treat everyone in your life as individual human beings.
I am notoriously stupid about celebrities so maybe there is some context I'm missing but I don't see the problem with Will Smith? He seems clean cut, handsome, intelligent, etc.
