He wished he could join the KKK, supported slavery, and bashed Martin Luther King Jr., all on an old porn website where he used to write.

Republican North Carolina gubernatorial candidate Mark Robinson referred to himself as a “Black Nazi,” disparaged Martin Luther King Jr., used antisemitic and homophobic slurs and spoke highly of slavery on a pornographic website before his entrance into politics, according to a new CNN report —as Robinson denies making the comments.

Among the revelations in CNN’s report were that Robinson called himself a “ Black Nazi ” and said “Slavery is not bad. Some people need to be slaves. I wish they would bring it (slavery) back. I would certainly buy a few.”
