I'm not going to answer that question. I am a Christian, and I don't think anybody asking a question about my religion is appropriate,
Imagine the situation: an economics minister is asked "Do you believe that increasing the minimum wage helps poor people?". His response: "I'm not going to answer that question. I am a Keynesian and I don't think anyone asking a question about my Economic Beliefs is appropriate".
This is just too completely ridiculous for words - if your religious beliefs affect your ability to do your job, then asking questions about them damned well is appropriate. Given that he didn't answer the question, this guy presumably is some sort of creationist, and this is certain to affect his decisions regarding funding for biology (evolution is the organising principle of the whole of modern biology - if you don't believe in it, you have to throw the whole lot out of the window). There is no reason why religious beliefs should sacred (and yes, I know that's a bad word, but I never have been able to think of a better one), any belief which makes you incapable of doing your job is fair game.
