Right, and if we were talking about people with Hillary's or Robert Byrd's record then I would decide that they weren't racist.
Hillary's record has shown a strong commitment to civil rights activism. Robert Byrd did do some horrible things, but he changed and apologized. The NAACP actually honored him after his death. Supporting the the KKK would prevent me from voting for any politician. But Robert Byrd actually changed. https://www.washingtonpost.com/blogs/post-partisan/wp/2016/0...

Whereas Trump has a history of racism. There have been accusations going back years, and his public statements support those accusations. He accused a federal judge of not being able to be impartial because the judge was Mexican. And David Duke is still a leading white nationalist, and said that voting against Trump is treason to your heritage.
People can change, but you can't claim they have changed if they've ignored what they did in the past and have not done anything different.
Do you think that Hillary is just as racist as Trump?
And are you voting for Trump because you actually want him as president, or because you think Hillary's worse?
