Shields stated that he had wanted to officially fight 'The Truth' in the octagon but learned Jackson was too scared to fight him after speaking to his coach:"On Twitter he started calling me a Nazi for no reason. I had no idea who he was... I'm extremely respected in the fight industry, everyone for the most part loves me and nobody has called me a racist, nor should they... I saw him [Mike Jackson] at the PI and I got in the cage and said let's fight."He added:"He kept making excuses saying we'd fight in Houston... I called his trainer and his trainer said he was scared of me. His trainer apologized and said he was an embarrassment... He said it's the last couple of months he's got into this black nationalism, hating white people."Catch the clip here:MMA Junkie@MMAJunkie"I didn't punch him because, you know, you punch men.
