Michael Moore tweeted, in response to the film American Sniper, "My uncle was killed by sniper in WW2. We were taught snipers were cowards. Will shoot you in the back. Snipers aren't heroes. And invaders are worse." Even Kid Rock criticized the Fahrenheit 9/11 director, writing "Fuck you Michael Moore, you're a piece of shit and your uncle would be ashamed of you."
