So the Irish have never fully integrated? What about the Scandanavians? How about the Germans? Maybe the Japanese?

While immigrant populations take some aspects of their homeland into their new country, they tend to integrate (as can be seen by the fact that 3rd generation immigrants do not speak their grandparent's language). Even if some of those groups live in isolated communities (as the Germans once did) they do not see their new country as a place for exploitation for their own tribal benefit, but a place where they can live their own lives better.

Or, perhaps you are going to tell me as a 7th generation Lithuanian immigrant, I'm actually just working to dominate America for the inevitable Lithuanian take over. Gamers Lithuanians Rise UP!

Or at least, I think it might be Lithuania, because no one fucking remembers and we consider ourselves American.
