"Certainly, people in our immediate community are more valuable than people we have never met in other continents. However, I don't think "community" should include beyond those who we actually interact with. It shouldn't include abstract groupings such as "state" or "nation". Supporting your high-school sports team is fine."

Yeah, wouldn't the world be a great place if everyone thought like this... screw helping the world... let's just help ourselves and those whom we interact with. Oh yeah, and while we are at it, why don't we completely cut off the less fortunate from our community so that they don't count as people we interact with.... then we can give even more money to our high school sports teams.
