Did you come to the US from another country and choose to become a US citizen? IF not then you had no hand in being a citizen. How can we be proud of things that happened to us as an accident of birth?
The same way I take pride in my sports teams...or my high school...or my nieces and nephews...and a ton of other things over which I have no control or input. And when OU has a player get in trouble as student athletes sometimes do, I am ashamed but I am still proud of OU's accomplishments. Yes, Lee Greenwood had it right.
