@Demosthenes I don’t know. If I heard it I guess I would have to go by context. Do they mean white culture? That term is hard for me too. White covers a lot of people for me, a lot of ethnicities and nationalities, so I don’t use the term white culture.
I use the term goyish with Jewish friends, which is the same as white bread. It would be people from the Midwest and South mostly, but no hard and fast rule. All types of people are everywhere. Mostly stereotypes about food, like ketchup on a hot dog, or mayo on a bologna sandwich. Also, an emphasis on alcohol, like alcohol at a wedding while other groups emphasize the food.
I think of them as almost completely, or completely, detached from their history before their family was in America. I am speaking as an American about Americans of course. I’d say many of those people are English, Scottish, and German, because they also tend to have been in America for many generations, explaining partly why there is a disconnect to the old country, but it really has more to do with where the person grew up in America in my experience.
By the way I made a typo above, hear not here.
