(D.B. Cooper)
When people suggest returning the Americas to the natives, I tell them that has already happened in some places. However, Nigerians, the Congolese, Mexicans, Haitians, Hindus, and other "independent" third world types can be seen on overcrowded rickety boats, heading to any country willing to take them in.

Is that what we can expect from Native Americans? I'm already picturing Kayaks full of Indians trying to cross the Atlantic, following the white people to Europe.

As an European, I say this to my American white brothers and sisters:

Agree with ones who want to return America to immigrants, now called "natives" or "first nations", who came to the continent before whites. Agree, but on one condition: all current population of the US needs to get out, nobody but "first nations" shall remain. When it happens, ask them "first nations" who they want to see back, and only those who they want to see back shall return.

Something tells me that if it happens, the US will be whiter than the Czech Republic.
