"I don't know why anybody would want to read fiction on this topic when there is such an incredible wealth of good nonfiction."

It's true there is an incredible wealth of good non-fiction on this --and other--topics. That does not negate that fiction has another, insight or emotion to add. One might just as well say why read John Steinbeck, there's so much good reportage, exposes and news reels out there regarding the depression.

Why sing songs about historic events...or current events?

Ron, you really disappoint with that comment.
