If we can't stop the theater from showing it, then let's buy tickets and throw toast at the screen.
Not just any toast.......french toast!
How many before theaters refuse to show it?
We can picket the theaters, where it is being shown.
Some suggested signs:
Michael Moore is a liar.
Michael Moore is a traitor.
Michael Moore is a media whore.
Michael Moore sucks.
I am sure that others can come up with some more ideas.
