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.

The CNN KFile investigation cited comments made on a pornography forum for the website Nude Africa under the name "Minisoldr." Details reportedly linked the profile to Mark Robinson.
