Doug has a great comment on the church-state separation issue. Go to his comment in the last blog entry for the explanation, but here is his summary:
The First Amendment embodies the simple, just idea that each of us should be free to exercise his or her religious views without expecting that the government will endorse or promote those views and without fearing that the government will endorse or promote the religious views of others. By keeping government and religion separate, the establishment clause serves to protect the freedom of all to exercise their religion.
Amen, I say.
