The son of Martin Luther King Jr. has blasted North Carolina GOP gubernatorial nominee Mark Robinson over his alleged “grotesque characterization” of his father.Martin Luther King III spoke out after Robinson denied claims in a CNN report that he made a series of offensive comments on the message board of a pornographic website a decade ago.

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.

North Carolina's Republican candidate for governor promised to stay in the race on Thursday after CNN reported that he once called himself a "black NAZI!" and proposed bringing back slavery in comments posted on a pornography website.
