Go fuck yourself.
Robert Byrd was elected to office in 1952 when segregation was the law of the land, and black people were still being lynched in the South. Byrd renounced his racist past and the harm he caused, and said that if he had to do it over again, he would have voted in favour of the Civil Rights Bill. He did that more than 30 years ago.
Here you are in 2020, endorsing a candidate for the Republican Party who is a member of a right wing hate group, and you think it's a good idea because 70 years ago, a KKK member was elected. Why would you want to have such a person in office, helping to determine public policy?
The idiocy of the modern Republican knows no bounds.
