Just like you build a house that can contain a family, you build a subsite that can contain a community. The term "house" actually conveys the impression that a family lives in it (and has the key to it), so we don't normally refer to such a building structure as a family house - and referring to it as a family is just plain wrong.
Those who cannot see this logic and, despite complaining that this is a pathetic non-issue, keep on protesting and thereby prolonging this discussion are the ones who are guilty of bikeshedding, IMHO. If the North Koreans have built yet another "nuclear power plant" while we were talking, you've got yourselves to blame...
Well, OK, I too have a small part in that guilt. 😊
