The author said "posting the data" is enough for backlash, they didn't say anything about judging the data, let alone that they'd judge the data like you say they would.
And even if they would draw "misleading" conclusions from the data, it is not helpful to rant at them and punish them, but rather assume their good faith (until proven otherwise) and explain to them why they were mislead by the data. Even if it's a bad white supremacist who'd never change their mind, you might still positively influence other people reading the same exchange instead of making other people root for the "underdog" (in that conversation) who was viciously and personally attacked just for posting data.
Most of the time people talk about “black on black crime” they’re not trying to make a sound statistical argument, they’re using it in service of some larger racist point. So yeah, when you start talking about “what about Chicago” or the shape of people’s heads, people tend to put you in the same bucket at everyone else who seems to be really interested in certain facts...
The problem with this approach is that if op was trolling then they could spit out a huge list of seemingly correct correlations that nobody would have time to debunk all of them. That would allow some of op's bad correlation to be left not debunked and appear that it is right.
In online forms you have to figure out if someone is trolling and then behave in one of two opposite ways based on it they are out aren't.
Absolutely socioeconomic and cultural factors affect the statistics. But they also affect statistics like representation in the tech industry.
If someone objects to bringing up one then the same person should object equally strenuously to bringing up the other. Which is not what happens in practice.
Lower cognitive ability is related with racism[0]. So it might not be malice, but simple that they cannot grasp the social underpinnings of such statistics.

I find it hard to believe that no one has mentioned the factors that make murder rate statistics misleading to you. At the very least, that it's being put out there with the implication that correlation is causation, and ignores other factors that have much more basis for a differing murder rate, like socioeconomic status.
It's probably the set of information that's put out there the most often in order to muddy the waters, often by people have racist motivations.
