I personally know of no great artistic talent of Condi Rice.
Gibson is a bit of a flake. He's not even as remotely conservative as some like to believe.
Stewart is truly the exception, as I suspect is Tom Hanks. There are always a few like that, but they're the exception not the rule.
I know diddley squat about Jean Stapleton or Ginger Rogers, so I won't say a word.
Duvall is a genuine actor, with all the baggage that it implies. He's about as weird as Depp living in the woods of France, only Duvall long since retreated to Argentina.
I could give examples all of day of artistic talents being truly weird individuals, and often broken individuals as a result:
Van Gogh, Hemingway, Dorthy Parker, Orson Wells, Marlon Brando, Robert Dinero, Robert Dinero (anyone that weird gets two mentions), Edgar Alan Poe, Edgar Alan Poe, Frida Kahlo, Dora Carrington, Mozart, Mozart, Beethoven, Stevie Ray Vaughan, Jimi Hendrix, Janice Joplin, Henrty Miller, Tennesee Williams, Oscar Wilde, D.H. Lawrence, Thoreau, Emerson, Judy Garland, Pavorati, Richard Burton, Joan Crawford, Bette Davis, and anyone ever named Barrymore.
That's just a quick list off the top of my head!!
Reagan was called "The Great Communicator"
and Condi Rice is the epitome of refinement and culture.
She's a classical pianist and trained ice skater, who could've gone pro with either.
The others have commanded extraordinary respect in their field, despite personal convictions and principles. Just google them and see for yourself.
I'm not defending individuals here, just the principle that
talent is a gift which people of great character use unselfishly.
Surely you don't think 'talent' just means 'artistic' do you?
