Buddy White people only become White once they came to America. The Immigration act of 1790 gave anyone White automatic citizenship to America.
This led to European settlers identifying as White. Before that, they considered themselves English, French, German, Irish, etc. White race is an American invention.
Romans did not see themselves as White, in fact they considered whiter skin people inferior and called them barbarians.
Ancient Greeks did not call themselves White people.
In fact only in the last hundred years did Greeks and Italians people become part of the White race.
Before America was a country, there was no such thing as White people.
Stop claiming things you had nothing to do with.
