>I encourage you to look at the data you yourself have posted and to draw your own conclusions.
This is quite irresponsible. You can't just leave it at "black men shoot more people than other demographics" and let the reader "draw their own conclusions", because on its own it seems very much like the conclusions you want the reader to draw are quite racist. On the face of it your comments look very much like other subversive racist comments that are often seen in less moderated forums than HN.
You want people to draw conclusions from incomplete data which only considers the subject's race. They'll draw on those conclusions to, say, vote. If you don't want to engender a racist perception, then you need to dig deeper than race before you state your arguments. How does it correlate with income? Job status? What are the schools like in these areas? How does it compare to other populations? America has an institutionalized racism problem, which creates an environment from which these problems arise in predominantely nonwhite areas. Don't mix up cause and effect.
Pointing out the demographics in this dataset, then complaining that no one wants to have that discussion due to some perceived social taboo, is a bad faith, racist argument.
