Double Consciousness, or a Lack of One

I do not even really know what my specific ethnic background is, nor am I from a specific religious background, and so I do not experience a conflict with double consciousness, as Du Bois suggest of African Americans. My conflict lies in that I feel like a have no national identity at all, and as for a specific national American culture which other backgrounds can melt into, I believe none really exists. I think it's important that immigrants maintain a strong sense of national identity once they enter America because as a nation, we should not surrender our identity to create a new homogeneous community, but rather draw significance from the "patchwork" of national/cultural differences which the U.S. has become.
