It wasn't until George Zimmerman that the phrase, "white Hispanic" was ever heard out loud in public discourse. I won't hold my breath for a logical defense of this torture of the English language.
I'll just keep an ear open for the eventual use of 'white Indian' or 'white oriental.'
Or the elusive white Siberian swamp negro.....
"Hispanic" has become a euphemism for "someone from south of the Rio Grande". The term can include mestizos (part native, part European descent), full natives who only speak their own language, etc.
It can also include people of 100% European descent who happen to have a Spanish-sounding last name. Like people from Spain.
I don't see why you wouldn't if Clarence Thomas can be white.
Clarence Thomas, to Washington Post, is ‘White’ thinker
