Our president is an atheist (more of an agnostic, but he does not believe in god, that's the point), and I have never heard him say anything meaningful on religion. So what?
Yes (catholic)
I mean, no religious politicians declare themselves as "agnostic" even if they don't believe in god at all.
If a president declares himself as "atheist", that would probably mean he's going to be be an anti religious president.
Well, not really. Why should he? Just because he does not believe in a god, why should he force this belief on others?
