Daniel Radcliffe believes it is important to separate religion and education because he thinks sex lessons are important.
The 22-year-old "militant atheist" was brought up in a Christian/Jewish household and told Attitude magazine he's not religious.
"I'm an atheist, and a militant atheist when religion starts impacting on legislation.
"We need sex education in schools. Schools have to talk to kids from a young age about relationships, gay and straight. In Britain it's better - more of a conversation is being had."
Radcliffe is interested in politics, but having supported the Liberal Democrat party in the last UK election he now thinks he is more of a Labour follower because he believes they stand up for more left-wing values.
"I will probably be going to Labour. From what I've seen of Ed Miliband I really like him and he speaks for what I believe in. I think he's genuine, genuinely left wing and will act as such if he gets in."
