WATCH: Leah Remini Refuses to Let the Church of Scientology ‘Bully’ Victims

Leah Remini said she “can’t sit back” and do nothing to help the people who speak out against Scientology.

The actress visited Ellen on Wednesday (Nov. 23, 2016), where she opened up about her experience with the Church of Scientology. “The people who are speaking are very brave to do it because [there are] repercussions to speaking out — and that’s why I said, ‘OK, I can’t sit back,'” she told Ellen DeGeneres.

Remini even claimed she has “been followed” since leaving Scientology. “But again, my story pales in comparison to what happened to other people, how people are bullied into silence,” she explained. “What I have is I’m an actress, and I’m able to speak, and I’m able to give a voice to people who might not have an Ellen to go on.”

So why do celebrities like Tom Cruise and John Travolta stay? “The Church does have all your secrets from when you were a child, but that isn’t the reason why people don’t leave the Church,” Remini, 46, said. “People don’t leave the Church because they actually believe what they’re doing is good. It’s very hard for me to attack something that I believed in, and I believed in it wholeheartedly my whole life. It’s a difficult position to be in.”
