Namely: Why would it be called "white EUROPEAN" when basically none of the people it is applied to are European in any reasonable sense of the word? They may have great-great-great-grandparents who were European, but that does not make them European.
Americans do this all the time - they call themselves "german", "irish", or "italian", even when they are not born there, do not speak the language, have never even visited the country, and have zero exposure to the culture of that country.
