Hey! You! Help Me Write My Piece On American Identity

I’d appreciate any comments on the notion of American identity:  what is it?  who has it?  should all Americans have it?  Do all Americans have it?  What is the American sine qua non?  Can we survive as a nation if we don’t have a shared national identity?  If not, why not?  If so, how would that work?

Use the comments section.  I’d love to know what you think.
