Robert Byrd left the KKK in the 1940s. Then he spent decades apologising for it, saying he had been wrong, and fighting FOR Civil Rights. THe NAACP said this of Byrd when he died:

"Senator Byrd went from being an active member of the KKK to a being a stalwart supporter of the Civil Rights Act, the Voting Rights Act and many other pieces of seminal legislation that advanced the civil rights and liberties of our country."[1]

Does this really compare to Trump's support from the KKK and his resistance to rejecting them?
