Obama Asks Students for 'Amen'
Seriously, if I asked for an "Amen" at a secular university, I'd get in trouble. The last time I was asked to give the invocation at a secular university, I was warned not to mention Jesus and not to ask those present to respond verbally to the prayer's conclusion. I seem to recall that I got a tatty letter about a week afterwards from the campus' alliance of atheists/agnostics/druids/wiccans, too.
Heck, once at a well-known automobile racing track in Connecticut, I was asked to open a race with prayer as long as it didn't mention God.
The other thing that was weird about this is that the President expected people to say "Amen" after a negative exclamation. In other words, "You will owe lots of money to a bank when you graduate. Say 'Amen'".
Government really is a religion in contemporary America.
