Having looked up what that means: am I missing something or is it the case that you don't want to interact with people who mention facts that can be used to support unpleasant narratives?
Because if so, that seems like a way of ending up with a very biased view of the world... while the murder ratio fact might be old news to you and something that shouldn't be dwelled on, there's bound to be one of the 10,000[1] just learning it for the first time and sometimes you'd be one of those 10,000 unless you cut yourself off from it.
You are missing that this is one of many racist signalers and memes white supremacists and nazis use to justify their hatred. They're based on incomplete and misleading statistics designed to manipulate people without critical thinking skills.
The best solution there seems to be teaching people critical thinking, statistics and how to look things up tbh... rather than cutting them off from these sorts of figures.
(I've personally been advocating that for a decade to anyone who'll sit still for a minute)
