I wouldn’t put my name on a book that organized cultures as American, European, African, and Asian, firsts of all. “Asian” isn’t a culture. “American” is barely a culture.
But if we actually narrow things down, what I would do with RL cultures is create descriptions of cultures with simple names, and give examples of countries and cross-national cultures that fit that category.
So, there would be Intelligent and Strong cultures from every continent.
edit: of course, I don’t actually like the design of putting ASIs in culture, so this is academic for me, but I don’t think that such a product would be called racist by anyone but an extremely small minority, unless the descriptions and specific representation was problematic.
