Michael Newdow, the athiest lawyer who tried for years to ban recitation of the Pledge of Allegiance, is now trying to remove the word "God" from our nation's currency. He claims it's an endorsement of religion and "excludes people who don't believe in God" according to this article.
Newdow's attempt to remove the Pledge went up to the Supreme Court, where he lost because he didn't have standing to represent his daughter, because he didn't have custody.
His argument for removing God from currency is that it's unconstitutional, and dismisses any claims that the reference is to the country's religious roots, "It's not the history that counts, it's patriotism. What it is, is these people want to get their religious views in our government."
Though I can see an argument against reciting the Pledge in schools, I'm afraid I'm missing the key point in removing God from currency. I can't see a harm in holding a piece of paper, or zinc, or nickel that has a word on it. I can't see that as an endorsement of any one religion, and I can't see it as trying to foist one's religious beliefs on another. This really sounds more like an extremist with an agenda who's not going to be happy until he finds some way to stick it to the system.
