There’s been some discussion lately on ditching the phrase “Delaware Valley” in favor of some variant of “Greater Philadelphia”. The reason given is that “Delaware Valley” allows (suburban) Philadelphians to dissociate themselves from Philadelphia.
I admire where the sentiment is coming from, but for now, I can’t see the language choice as important enough to police my own language or scold anyone else for theirs. This may change in the future, or it may not. Still, I thought I should make a note for those as do care.
