The separation of church AND state is designed to protect both state and church (religious freedom). Though we should do nothing to suggest that one religious viewpoint is a "state religion", that said, I do believe much of our law / interpretation of the law is way overboard. If someone wants to pray in class or hold a bible study after school, one should be allowed to do so. If a pastor delivers an invocation and closes with "in the name of Jesus".... so what? It will cause no one any harm. However, the same people that endorse an Evangelical pastor's prayer need to offer the same respect to a prayer of an Imam. My guess, however, is that most won't endorse the two-way street here, which is why people get uptight about the Evangelical pastor's prayer.
