I would ask: What did you say or do as the shooters retreated into their xenophobic silo and consumed the bile slouching about the Internet? What did you say or do as the darkness in their hearts obscured the light of their reasoning, and the vacuum of hate consumed them?
My suspicion is that far too many do far too little.
So they’re in a silo consuming bile—which is, somehow, slouching—while their reasoning is “obscured” by dark hearts. And while consuming this bile, they’re being consumed in turn by a “vaccum of hate”—possibly located in the silo, on the Internet, or perhaps even in their dark hearts. I’m pretty sure this paragraph counts as a hate-crime against readers.
