jimbojabba, it is near impossible to term anyone 'black' or 'white'. Even just in the USA, discounting many white folks that have at least one African ancestor in their pedigree, what would you class the half black/white folks?
Does black include the lovely shades of caramel, common with the Pacific basin Natives? What about the Australian Aboriginese, they are even blacker than Jamaicans.
I think defining someone by their colour could be seen to be offensive. During or before WW11 very high ranking german officers, lawyers etc got togethor to decide how Jewish people could be i.e. If your grandma was a Jew then did this make you a Jew. I could not believe this happened. To me it was so ludicrous it was 'Monty Python' esk in its utter stupitidy.
Sorry I must be lacking some education as it is not obvious to me who is black or white. And though important to you it is not to me!
