I don't know if this technically qualifies as the Webster's definition of irony, but if it doesn't it should.
Per the story on TheBlaze.com:
White supremacist Craig Cobb has been buying up land in a small North Dakota town to create a haven for others who hold beliefs similar to his own. Cobb, whose intentions in Leith, N.D., were at first somewhat secretive and quiet, has been more vocal lately.
Cobb recently appeared on “Trisha Goddard,” a NBCUniversal talk show, for an episode that will air Nov. 18 as part of the host’s “Race in America” series. On the show, Goddard revealed the results of a DNA test Cobb had taken, finding he had some African decent. His reaction? Amused denial.
