Sarah Palin has never been one to shy away from controversy — and now she’s jumping into a new one over the film "American Sniper." On Friday, Afghanistan war veteran Dakota Meyer posted a photo to his Twitter account of himself and the former Alaska governor and vice presidential candidate holding up a sign that said “F— you Michael Moore,” with the Os in Moore deliberately drawn as cross-hairs. In a blog post, Palin’s daughter Bristol confirmed that the photo was indeed really Sarah Palin. The sign was a response to a controversial tweet in which Moore, a documentary filmmaker known for his left-wing views, called snipers “cowards,” saying: "My uncle killed by sniper in WW2. We were taught snipers were cowards. Will shoot u in the back. Snipers aren't heroes. And invaders r worse.” After receiving backlash from conservatives and supporters of “American Sniper,” Moore elaborated on his comments on Facebook but did not back down, clarifying that his comments were in reference to snipers but that he was not specifically commenting on the film.
