Did he edit his comment? He's obviously failing at reading comprehension, but I don't see how his comment is a political rant in any way. He's (incorrectly) pointing out Vox's bias in the way they present data.

Personally, I also don't trust anything on Vox after they posted this debacle of statistics last year: http://www.vox.com/2015/10/3/9444417/gun-violence-united-sta... which attempted to make a point on why gun control was so needed while completely failing to control for suicide (the most common cause of gun related death) and trying to make points about how gun control lowered suicide rates (by gun) while failing to note that a link between overall suicide rates and gun control has not yet been established by any study.

While this particular poster is simply wrong about the data presented here, I would hate to think that anything that doesn't conform to a left-wing viewpoint on HN would be considered "political" just for that reason.
