Tell us how you really feel! Former That ‘70s Show actor and practicing Scientologist Danny Masterson sounded off on critics of his religion in a candid (and expletive-filled) interview with Paper magazine, conducted at the Sundance Film Festival ahead of the premiere of controversial documentary Going Clear: Scientology and the Prison of Belief. Masterson, in short, told the mag that those who think his religion is “weird” can “go f–k” themselves.

"I heard about that documentary; the documentary where they interviewed eight people who hate Scientology. Should be pretty interesting. I wonder if Sundance would allow a documentary of, like, eight people who hate Judaism. But you know, my religion's fair game, I guess, 'cause it's new," Masterson told the mag, before going on to detail his religion and those who frown upon it.

"There's basically like 200 lies in the book and so therefore he couldn't even publish that book [in Canada or the UK because of the libel laws],” he added, referring to Lawrence Wright’s book, which inspired the buzzed-about documentary.

Masterson, who started practicing the religion at age 8, went on to explain that it’s hard to explain Scientology to those who haven’t read founder L. Ron Hubbard’s book Dianetics. Essentially, he says, “Everything in Scientology is just based on logic…the word Scientology means the study of knowledge.”

“There’s nothing else to it,” he adds. “It’s literally just that.” When it comes to his “personal relationship” with founder Hubbard, Masterson candidly added: “He’s a f–king guy who wrote awesome s–t that I love studying.”

After explaining the roots of the religion, Masterson then discussed the battle between Scientology and psychiatry, and, not to mention, former follower Paul Haggis, who left the church on account of gay marriage.

“You will not find a Scientologist who does not f–king hate psychiatrists,” he sounded off. “Because their solution for mental and spiritual problems is drugs. So let's talk about putting a Band-Aid on something that's just going to get worse and worse and worse…[where as] Scientology handles those things, those mental problems that people have. It gets rid of them. It gets rid of them by that person doing it for themselves. That's the solution to depression, not f–king Prozac.”

As for Haggis, Masterson said his anger “had nothing to do with Scientology.”

“[It’s] so stupid. What Paul was angry at made perfect sense, but it had nothing to do with Scientology,” he explained. “Paul was just mad that, as a religion, we're not going to come out and say that we are for or against anything, which is a political matter…It’s like, ‘We have no opinion in the world of politics. We are a religion.’”

The interview with the magazine was a first for Masterson, who said he had yet to openly discuss his philosophy before. But it likely won’t be the last.

“I love doing it and have no problem doing it,” he concluded. "I work, I have a family and I'm a spiritual being who likes to understand why things happen in the world and want to learn more so that I can have them not affect me adversely. So if that's weird, then, well, you can go f—k yourself."
