So many of then keep saying 'we are a community", "our little community" and so on. Who is this "community"?, the country?, the state?, the town?
Politicians love saying for 'the community" and "us the community" like it's some kind of buzzword. I think this is just some tribal mentality of us versus them.
The extent of the community depends on the context. I think most Americans when they hear the word would think of the people in their neighborhood or town. But it can mean any group of people, like a university, the LGBT community within a city, an internet fandom message board, etc. When a politician or elected official is saying "community" without prefacing specifically what community, they are probably referring to someone's local town or neighborhoods.
