"American" is often thrown around as a pejorative on this board for surname-names (not by everyone, of course). Though, I'm curious -- do you dislike these sorts of names on Americans as much as you dislike them on Brits?
I thought of this when I was reminded that the current US Democratic presidential candidate Joe Biden has a son who goes by Hunter (Hunter is actually his middle name, which was his mother's maiden name, but he seems to go by it exclusively).
