You seem to be arguing with something nobody said. There's no assertion that WASPs are the only people in the world to have ever decided that one sort of naming convention is normal.

What is being said is that our particular notion of names comes out of that WASP tradition. (Which, if you'll take 30 seconds to read Wikipedia, has important class and wealth connotations.) And therefore it doesn't apply perfectly to an extremely diverse society of immigrants, one with a long history of cultural, religious, and social experimentation.

It's an accident of history that a dominant strain in our culture is "protestants from the British isles". But it's still a pretty important accident. It leaves a mark. We still call that part of the country "New England", for example.
