Really, do we want to go around insisting that we are exceptional? Are we better than everyone else? Don't you remember hating the big, swaggering bully who pushed people around on the playground. It makes people want to bring you down a notch when you say you are better than them. It makes them want to get even, it makes them hate you.
We should quit kicking the world's hornet's nests, and start taking care of the poor, tired huddled masses we already have here.
