Michael Green Has the Right Idea
Dogs never did a thing to anyone. In general, dogs are nice creatures who wouldn’t hurt a fly (on purpose, anyway). Dogs didn’t punch a huge hole into the ozone layer. That was us. We humans are responsible for most of the world’s problems, not canines. Let them in our libraries!

Oh, it’s fine for rabbits, sheep, and evil penguins to go into libraries but not dogs? What did dogs do that made this library so mad? The librarians are going to regret this poster when Michael Green of Twitter marches into the library with an army of 100 (evil) penguins in tow.
