The First Amendment states, "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof." There is nothing said about the separation of church and state in the foregoing sentence.
The First Amendment, as written, gives the citizenry the option to practice any religion they want or to practice no religion at all. It's your choice, not a politician's.
Inviting the clergy of a city or state to say a prayer asking for guidance and clear thinking prior to a governmental activity is certainly not making a law establishing any religion. And some of these hacks could certainly use the guidance. If you want to take part, fine; if you don't, also fine.
Also, "amen" is not an affirmation to Jesus Christ. It is a word derived from the Latin, Greek and Hebrew meaning, "truly," "certainly" or "so be it." It can also be used after a prayer to express approval.
