@ThatCrazyDude @silas you think that Americans is one homogeneous ethnic group? There are people here from all over the world. There's no ethnic American like there's ethnic Germans.
And there's a lot of reasons for that, but it's mostly for census reasons. The census is used to apportion representatives in DC, but the census isn't limited to citizens. If the census was limited to citizens, New York, Washington State, New York and Illinois would all lose seats, which means they'd lose power
