Was Mark Twain Racist?

Mark Twain often made funny remarks about people of different cultures. His remarks appear racially inclined to some, though he was not a racist. In fact, he has categorically quoted that he does not have any color prejudice. Having endured the ravages of the American Civil War, he deeply empathized with minorities and slaves. It is my opinion that Mark Twain was not racist. Here are some quotes that might shed more light on the topic.

• Whenever the literary German dives into a sentence that is the last you are going to see of him until he emerges on the other side of his Atlantic with his verb in his mouth.
  
  
• Our most valuable and most instructive materials in the history of man are treasured up in India.

• In Boston they ask, how much does he know? In New York, how much is he worth? In Philadelphia, who were his parents?
  
  
• It was wonderful to find America, but it would have been more wonderful to miss it.
