America has a less then perfect past itself, servers examples, the near annihilation of an entire culture (the native Americans), the deliberate destruction of a species for sport (i cant remember which for this but i remember it coming up on the amazing program that is QI). The past of a nation is no reason to determine its future. You know as well as everyone on here that things change over time. Remember there was a time not so long ago when Europe was very divided. Also your history is our history as server pointed out. The current american population are almost all of European decent.
