Of course, if you refuse to discuss race and crime, someone will point out that more blacks get arrested than whites and claim that this is due to police racism. More generally, once you start lying the truth is ever after your enemy.
The only person who might be considered as pointing this out here is you, I will observe.
For example, you may have heard that social science is in the midst of a replication crisis, well there is one area of social science where that isn't the case, namely IQ research and its correlates. Of course, for most social scientists openly stating that differences of race or gender are significant, or really anything that makes a black, woman, LGBT, or other member of a protected category look bad is career-killing. Hence social scientists are reduced to doing data dredges which unsurprisingly don't replicate. The current state of social science is like what astronomy would be like if astronomers weren't allowed to say anything that might imply the earth might not be flat.
The difference between my intelligence and the intelligence of the average person who makes this argument makes this look, to me, like a bunch of bank robbers, engaged in an argument about how to split their latest prize, accusing one another of theft for trying to argue they should get a bigger take for their particular roles. Which is to say - almost everybody is less intelligent than me, by quite a margin, and certainly a larger margin than may exist between the races. If you want to argue that racism is acceptable on the not-nearly-as-solid-ground-as-you-seem-to-think that black people are less intelligent on average, you're going to have to justify what makes the measures your side intends to take against black people less appropriate if I intended to take them against you. If you think they're subhuman, well, you're sub-me.
But even if you leave me out of it, and there's still somebody smarter than you. While you consider what to do to -your- lessers, consider whether you want your betters to follow your example.
Of course, history also says that people who spread false beliefs about equality are much much more prone to criminal behavior (or at least behavior that would be criminal if the people doing it weren't in charge of the state). This is a special case of the danger posed by people committed to readily falsifiable and false beliefs.
I have little patience for affirmative action and other "social justice" forms of collectivism, because I see where that leads. I have less patience still for collectivists who pretend that their collectivism isn't really collectivism, or who espouse a different kind of social justice - because racial meritocracy is just social justice by another name. Indeed, racism is and was widely practiced in collectivist societies, whose crimes you allude to here.
This sort of thinking seems bad:
This sort of thinking seems socially frowned upon, but accurate:
Similar points could be made by replacing a/b with [group of people]. I think it's terrible to say something like:
But to me, it doesn't seem wrong to say something like:
Credit and accountability seem like good things to me, and so I want to live in a world where people/groups receive credit for good qualities, and are held accountable for bad qualities.
I'm not sure though. I could see that there are unintended consequences of such a world. For example, such "score keeping" could lead to contentiousness. And perhaps it's just something that we as a society (to generalize) can't handle, and thus shouldn't keep score.
