I wouldn't assume there is such a thing as a single, monolithic "white culture", to start with. (Or black culture, or Latin culture, or...)

Stuff White People Like describes what is specifically the culture of coastal urban white hipsters, which is a relatively small subset of white people in the US. It's really inaccurate to think of those traits as "white culture" period. And I'd call what SWPL does with its subject matter less "celebration" than "savage excoriation". Maybe the people it describes don't take it so; I don't know. I've never yet knowingly run into anyone who took it any other way.
