Why do white Americans think they have no culture?

[Ferguson97]

Because "white culture" is a meaningless term, just as "Latino culture" and "Asian culture" are meaningless terms because of just how many countries that could mean. Italian vs Irish, Mexican vs Puerto Rican, Japanese vs Korean... extremely different cultures.

In an American context, "Black culture" has a very specific meaning because the overwhelming majority of Black Americans are descendants of slaves and may not know what country their ancestors were taken from. It could be Chad, it could be Senegal, it could be Nigeria. They don't know.

Most white Americans do know where their ancestors came from. Mine came from Ireland, England, Scotland, Italy, Wales, and Canada. I have an interest in my Irish ancestry and usually answer "Irish" when someone asks my family's background.

So "white culture" is sort of a meaningless term.
