MrsTerryPratchett, blacks number just under 13% of the United States. Whites are 72%.
Therefore if whites refuse to vote for a black President regardless of merit, the US would never have a black President.
Whereas even if 100% of black people vote for the black candidate, then that won't be enough for him to win without white votes.
In American demography, people are Hispanic, white, black, Asian, and Native American.
In all other contexts Zimmerman would be described as Hispanic.
I am not sure why you have linked to an article on Central America. Zimmerman's mother came from Peru.
I don't feel persecuted. Racism is a complex issue. Blacks in America have many problems within their own communities entirely independent of white influence, entirely black cities like Detroit are disaster zones for example. No doubt young black males are more likely to be regarded as suspicious than little old white ladies, but that is also reflected in respective crime statistics.
The process seems to have been that Trayvon was shot by Zimmerman, people assumed he was a white Jew and Trayvon is clearly black, and therefore it was de facto a racist killing, just like every time a black crook gets beaten up by a white cop it's also racist, whereas if a white crook is beaten up by a white cop it's just a cop being overly enthusiastic. When people found out that Zimmerman was in fact Hispanic, and not a member of the white male George Bush-type supremacy, he was hastily redefined as white Hispanic to fit the ongoing nasty white racist shoots poor black kid narrative.
My guess is Zimmerman was probably pretty quick on the trigger, but it's absurd to say that every time a white man shoots a black man it mus tbe racist. Really ridiculous.
I went to a neigbourhood watch meeting once, and the lady (ethnically Chinese, though culturally English) who was the energy behind the various local neighbourhood watches was clearly paranoid about crime. She said she kept a baseball bat under her bed, and made it clear that she would batter any intruder who came into her house. I don't think that makes her a racist, just someone who has the fear of crime blown up out of proportion (the area we live in has very low crime, and our car insurance fell 25% when we moved here). Likewise Zimmerman by his active membership of a neighbourhood watch was more paranoid than average, but there's nothing at all to suggest he was racist.
