I don't think that there is a problem with bringing religion into politics, even though I'm not religious myself.

The separation of church and state is essentially a good thing. I don't believe any religion should be given arbitrary precedence over another. However, that is different from separating religion from the state and the business of government. The thing is that the state is ultimately made up of people, and many of these people are religious. That is the way they work and the way they think. If their values are based on their religion then that's fine. All our values are based on something. If you don't like fundamentalist-Christian values then don't vote in fundamentalists. But so long as they preserved religious freedoms and equality then I see no problem if, should they be elected, they governed by their own values.
