Liberal filmmaker Michael Moore launched a broadside attack on the use of military snipers in warfare to mark the release of the Oscar-nominated movie American Sniper.

Directed by Clint Eastwood, the movie is based on the life of Navy SEAL Chris Kyle, and received Academy Award nominations for Best Picture, Best Actor and Best Adapted Screenplay. It is projected to take $105.2 million over the Martin Luther King holiday weekend.

Yet Moore remains far from impressed.

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 — Michael Moore (@MMFlint) January 18, 2015

A few hours later, however, the Fahrenheit 9/11 director qualified his outburst somewhat.

But if you’re on the roof of your home defending it from invaders who’ve come 7K miles, you are not a sniper, u are brave, u are a neighbor. — Michael Moore (@MMFlint) January 19, 2015
