It would be very interesting to find out that he isn't.
Every story out there is he's half WHITE, and half BLACK.
The very fact that he run's as a "black" man...proves the old Hawaiian surfer / local thing.
Didn't matter much if you were white and could surf better than the local "brown skinned" "bro's"....unless you just shredded way better!! Even then..it was very hard to be accepted.
It was all about color!! Period. Half brown, half black...didn't matter..you were in, over the white guy.
