I have seen the videos and heard the statements by the Aztlan/ LaRaza folks about the Europeans (white) going back to Europe.
Now, in the North, the Indians (Iroquois, Cherokee, Creek, Seminole etc )mixed with the Europeans ( English, Irish, German etc. and produced North Americans.
In the south the Indians (Aztec, Myan etc. mixed with Europeans (Spanish). They keep saying that the Europeans need to go back to Europe, are they going too? Theyseem to conveniently forget that they are European also.
