Actor Gary Sinise has taken exception with former Governor Howard Dean’s comments regarding the moral ambiguity in Clint Eastwood’s American Sniper.

Dean appeared on HBO’s Real Time With Bill Maher Friday night and the topic of the polarizing film came up on the panel. Dean had strong words for the film and the way Kyle wrote about the “savages” in Iraq, and voiced his hatred for the Iraqi people in general.

Here is the clip from Real Time:

Gary Sinise has since blasted Howard Dean on his comments on the show. Sinise, who is a staunch veterans advocate, and who played wounded Vietnam veteran Dan Taylor in the 1994 Best Picture winner Forrest Gump, wrote an extensive retort to Dean’s reaction.

Sinise’s comments were extended on a celebrity website:

“You certainly have a right to make stupid blanket statements, suggesting that all people who see this film are angry, but how is that helpful sir? Do you also suggest that everyone at Warner Brothers is angry because they released the film? That Clint Eastwood, Jason Hall, Bradley Cooper, Sienna Miller and the rest of the cast and crew are angry because they made the film? Chris Kyle’s story deserved to be told.”

Gary Sinise also credited American Sniper for showing the stress “our defenders” go through to preserve freedom, despite Howard Dean’s opinions. He concluded by saying “I will admit that perhaps somewhere among the masses of people who are going to see the film there may be a few that might have some anger or have been angry at some point in their lives, but, with all due respect, what the hell are you talking about?”

Gary Sinise and Howard Dean are not the only celebrities who have been embroiled in an argument over American Sniper, which has continued to dominate the box office. Last week, Michael Moore had to clarify comments he made about snipers in general. Aside from Moore, several critics and advocates for the film have battled it out on social media.
