Most people I know I think agree and even many theists agree with this. We don't want government involved. When atheists become the majority in this country, I don't think the theists are going to be glad to have "one nation under no God" inserted in the Pledge of Allegiance.
I feel like I am not an American in the eyes of my government because of their religious beliefs. I think that is un-American.
I think the Constitution has been upheld. I think they made the right decision.
A lot of God-loving people think that killing people who don't agree with them is OK.
