The "but black people are more likely to be violent criminals" rebuttal is a despicable one, and if you can't see the absence of causal links that you're deliberately hopping over in an attempt to shoehorn that in, then I doubt I'm going to make you see it in a HN comment. That said, I sure hope you don't ever correct someone on "causation vs correlation", as you'd be a tremendous hypocrite.
Notably, we can correctly observe that black people commit more violent crimes per capita than other races without implying any of the following:
1. black people are biologically disposed to crime
2. a significant percentage of black people are criminals
3. any given black person significantly more likely to be a criminal than any given non-black person
I definitely think your decision to pick your battles more carefully is the right one, and I encourage you to be even more judicious.
Maybe take some time to compose yourself, scan the HN guidelines, etc before commenting?
Enjoy your day, Literal Statistician. :)
