When quizzed on the religion's most famous poster boy, Leah explained: "Parishioners believe that [Tom Cruise] he is single-handedly changing the planet because that is what the 'Church' is telling them."
One user asked the actress what the most horrible thing she'd witnessed the church do, Leah's response was worrying.
Another common question on the reddit thread was whether ex-Scientologists could support each other, according to Leah it's simply not an option.
"Do the higher ups know it's a scam or do they really believe this crap?" One fan questioned.
"I actually do not know. Ask the LAPD," Leah said.
"I feel very safe. I have the support of my family and friends. And, I feel strangely protected by the world at large."
