More recently, Oren Jacoby's "Constantine's Sword," based on James Carroll's best-selling book, traces the roots of violence and intolerance within Christianity.
One of the places the film takes audiences is the U.S. Air Force Academy in Colorado Springs, where chaplains and the administration aggressively pursue a policy of proselytizing, where Jewish cadets are called Christ killers, where basic training includes not only physical and mental exhaustion but a haranguing by the chief chaplain for a) not being Christian, or b) if they are Christian, not proselytizing enough.
After seeing the film, Michael Weinstein, a cadet's father, founded the Military Religious Freedom Foundation, a sort of clearinghouse for abuse in the military. A soldier serving in Iraq wrote to the foundation, saying that as an atheist he was hazed to the point where he feared for his life by fellow troops who were evangelical fundamentalists. A lawsuit against the Department of Defense has recently been filed on the soldier's behalf.

"People have sent us e-mails saying they're spending the summer helping Katrina victims, or when they were touring Europe, they went to a homeless shelter."
Screening at prisons, senior citizen centers, juvenile detention centers, among other places, Belic said, "Friends of mine ask me, 'Dude, who's going to buy this? Why are you showing this here?' I tell them, 'Dude, that's not what this is about.'"
