My uncle got my my wife and I tickets to see The Scottsboro Boys in the West-End for Christmas. It was awesome; funny and affecting with a late, optimistic coda. That said generally the entire story was pretty grim (racial oppression and a brutal miscarriage of justice. But with catchy tunes!) which is even worse if you read the actual history of what happened.
But I got to thinking about how much things have improved. I’m an optimist and a believer in the steady march of progress so I got to wondering; why would anyone not be? How could someone want social/scientific/cultural progress to slow down, stop (or in the case of reactionaries) reverse?
