Whenever there is a mass shooting, segments of the general public respond with "thoughts and prayers" -- you can see this on your Facebook feed, or in any run-of-the-mill news article. People make statements like "thoughts go out to the victims in Orlando..."

In the linked game, if you tap "think" and "pray" a few times, you eventually get an option that says "ban assault weapon sales." The point of the game is that thoughts and prayers are ineffective at reducing shootings. The author proposes banning assault weapon sales instead.

I think OC was being sarcastic.

Also "thoughts and prayers" are the standard political response from GOP senators and congressmen. Many think they should do their jobs and pass legislation to help keep the public safe, like is done in the automobile industry for instance. Thoughts and prayers haven't helped...ever.
