I know religion causes a lot of issues in society one way or another. Money is probably spent like crazy on it, for one, but I'm looking for some common sense numbers to put to that and other points. Basically I just want to be able to support the statement "religion is a social problem" with sensible facts. I guess I'm advocating the "religion is poison" stance which is pretty hard to justify, I think, but I want to try. Just trying to enlighten myself on the position religion has in society.
