I am German, because I was born to German parents. You are Americans because you were born to American soil.
Actually I'm what we call in the south "a fence climber"

A mixture of German, Swiss, Scot, and English (that I know of), all immigrants dating back to 116 years prior to the American Revolution. Unlike many Europeans who's lineage is more limited, we do consider ourselves Americans first, that's who we are, but because of the melting pot nature of our country we can share the customs of others without bias.
