Ann Arbor, Michigan teen Katy Butler is protesting the Motion Picture Association of America's (MPAA) decision to give the documentary film Bully an R rating.

In the documentary, which is being distributed by The Weinstein Company, viewers meet the victims of bullies, including 12-year-old Alex from Sioux City, Iowa and 16-year-old Kelby from Tuttle, Oklahoma. Kelby's ordeal began after she came out gay.

The MPAA said the film's R rating is due to six expletives heard in the documentary.

Butler, 17, launched a Change.org petition asking the MPAA to lower the film's rating to PG-13 so that younger students can watch the film. She delivered more than 200,000 signatures to MPAA officials on Wednesday.

“I think it's an absolutely powerful, wonderful movie because these are real kids and they're telling their real stories,” Butler said during an appearance on CNN. “The language in this movie is part of what makes it so powerful.” (The video is embedded in the right panel of this page.

Butler said she became the victim of bullying after she identified as a lesbian.
