This habit needs to be broken...

Instead of holding tearful vigils for the recently departed, or becoming proficient in hastily constructing sidewalk memorials, or going viral with tweets, or brilliant displays of hindsight and hand-wringing, wouldn't it make a hell of a lot more sense to do something constructive about the misinformation around the Second Amendment and the NRA and the nutcases who can legally obtain and use lethal weapons? I like Americans, but you really need to stop killing each other, and start remembering the sixth commandment, 'Thou shalt not kill'. 

If you look that up in Exodus 20 or Deuteronomy 5, you won't find any exceptions; it simply tells us not to kill one another. It doesn't say anything about 'except when I'm really angry' or 'except when I've lost my mind' and
it also doesn't mention any Second Amendment. It just says "Don't do it!".
How difficult is that to understand? Remember, there's only one God, and it isn't Wayne LaPierre and his NRA. And you can bet your sweet bippy on that one.
