Julianne Moore has added her voice to the calls for increased gun safety measures, launching a campaign to help prevent gun violence.

The Oscar-winning actress has teamed up with Everytown for Gun Safety, the largest U.S. gun violence prevention organization, to start the Everytown Creative Council, a group of actors, artists, and more who support gun violence prevention.

“As actors, we are citizens first so we believe in the Constitution and the Second Amendment,” Moore told PEOPLE. “But 92 percent of the people in the United States are in favor of background checks, too, so I don’t feel like I’m in the minority. I definitely feel like I’m in the majority.”

Moore, a mother of two, said she was inspired to join the campaign as a parent, after the 2012 mass murder of 20 children and six adults at Sandy Hook Elementary School in Newtown, Connecticut. “I was like, ‘I’ve had it,’” she said. “I said to my husband, I’ve got to do something. This is the one thing that I need to say something about. This is my responsibility as a parent.”

The Everytown Creative Council calls for increased gun safety awareness and measures to “keep guns out of the hands of dangerous people.” To date, 79 members of the creative community have joined the Council, including Kim Kardashian, Jennifer Lawrence, Aziz Anzari, Steve Carell, Amy Schumer, Seth MacFarlane, Ellen DeGeneres, Mindy Kaling, and more

“I was going through my address book alphabetically. That’s all I did,” Moore said. “‘Please, are you interested,’ and the response has been overwhelming. I’m so, so thrilled. Everybody feels this way about this issue. I feel like with gun safety, there have been many people who feel threatened by saying something, but I don’t think I’m saying anything that’s unreasonable. With all of these rights that we have in our Constitution come a great deal of responsibility, and I think the founding fathers would agree with me.”
