How? Just by being? I and my family and friends live in a big city. Am I a cancer? I’d like to think that someone can be part of a big city, small town, or live in a shack in the woods and still be part of something positive. Quit with the generalizations that have no basis in fact.
You know what I mean; but if you don’t, then you are way behind. “...big city, small town, ...shack”, two out of three are fine.
