"The academy has been under investigation because of complaints that evangelical Christians have harassed cadets who do not share their faith, in violation of the constitutional separation of church and state."
Ummm, can you see it now?
Now you're moving the goalposts. We were discussing whether people claim the constitution literally contains the words 'separation of church and state'. Of course it doesn't, and nobody has come up with a quotation where anyone said it did. Now you're discussing whether it entails the idea of a separation of church and state. People differ over that.
