It's The Onion so you know it's supposed to be funny

One of my friends linked on Facebook to this story about a sad AR15 that sits on a gun dealer's shelf waiting to be sold so it can go out and start killing people. In the first place, there's no AR15s sitting on any shelf anywhere because every one of them has been sold since December.

But I left her a comment:

So many already sold, so many never killed anyone. But so many standing ready and prepared to defend the lives of their owners.
 

Two of her friends already liked my comment. It might be the best thing I ever wrote.
