The Babylon 5 episode, "Parliament of Dreams" is about showcasing different alien culture's belief systems and ends with a display of "Earth's dominant belief system." Unlike all the other ceremonies which feature stories, chants, drums, and bells, the Earth celebration introduces, one by one, a loooooong line of at least 40 people, each representing a different belief system:
Atheist (I love that this is first!)
Moslem / Muslim
Not all are named, and of the ones that were only shown I, sadly, recognized only a few.
I leave it to the reader to take away the appropriate lesson.
