Madonna has staunchly defended her devotion to the mystical Jewish teachings of Kabbalah.
"It would be less controversial if I joined the Nazi Party," she said. The pop queen admitted she found it strange that her religion disturbed so many people, but put it down to a lack of understanding.
"It's not hurting anybody," she said. "'What do you mean you study the Torah if you're not Jewish?'"
"'What do you mean you pray to God and wear sexy clothes? We don't understand this.' It frightens people. So they try to denigrate it or trivialise it so that it makes more sense."
The 47-year-old said she could relate to Tom Cruise, who has been ridiculed for being a Scientologist.
"If it makes Tom Cruise happy, I don't care if he prays to turtles," Madonna said. "And I don't think anybody else should."
Guru 'extortion'
The singer spoke to the New York Daily News as it emerged that the Kabbalah guru credited with persuading her to make a pilgrimage to Israel last year was arrested for allegedly extorting a cancer-stricken woman out of some £28,000.
Shaul Youdkevitch was accused of convincing a Tel Aviv couple the woman would be healed if they donated large sums of money to the Kabbalah Centre.
Madonna said it made her particularly angry when the religion was portrayed by the media as a cult.
"We're all in a cult," she said. "In this cult we're not encouraged to ask questions. And if we do ask questions, we aren't going to get a straight answer. The world's in the cult of celebrity. That's the irony of it."
The singer-turned-children's author dismissed the notion that she has become ultra-conservative and "preachy" in her older years.
"What do you call 'preachy'?" she asked. "Having an opinion? Guilty as charged!"
Defending her famed refusal to allow her two young children to watch television, she added: "It's not conservative. It's actually very punk-rock to not watch TV."
Madonna, who is promoting her new album Confessions on a Dance Floor, said she had given up on acting but wanted to direct.
But she insisted her singing career was far from over. "I'm not thinking of quitting," she said. "I ain't going nowhere."
