Zimmerman has to be nuts.
He must be addicted to the spotlight and stir things up.
Or he’s desperate for money.
Or He thinks he the money he gets will be worth the beatdown.
Or he’s trying to cash in on fame in other ways such as art sales and trying to extend his 15 minutes.
Or he could think that letting a black beat him up in the ring, might dissipate some of the racial hatred towards him.
