Yes, afraid so. Hispanics ARE white. There are only 3 racial stocks, and they don’t fall under Mongoloid (East Asian, Pacific Islander) or Negroid (African.) Texas driver’s licenses list them as “white.” They are “Caucasoid.”
Ethnicity is another issue altogether, and is often confused with “race.”
The pre-Columbian (Indian) inhabitants of North, Central and South America migrated there from Asia. How can a descendent from that group be white?
There are Hispanics who are entirely of European extraction. For example, the proudly Castillian of Cuba, the Old Spanish ruling class of New Mexico, etc.
Then, you have the Mestizo people, mixed race, native “Indian” and European. Brown people with European surnames.
And then again, there are Hispanics of African ancestry, or mixed, with either native “Indian,” European, or both.
The “white” Hispanics actually are white, being wholly European. They look down upon the Mestizo. The Meztizo are lighter than either the purely native Central Americans or those Spanish speaking people of African ancestry such as Cubans or Puerto Ricans, those who are not Castillian at least.
It's an entirely fictional construct. They're no more a united, distinct racial group than English speakers are.
The shooter, Zimmerman, appears Central American, being stocky, not particularly tall, and brown. He'd be on the next to the bottom rung of the Hispanic pecking order, if it weren’t for the surname, and I believe that might even belong to his godfather, not bis biological father.
This was not a white on black shooting, no matter how you spin it.
