It is a reality that you will have to cope with, fellow americans.
Just forget that whiteness is a concept that always have been changing in American history: from the 17th century to the mid-19th century Irish people weren't considered whites; until the end of WW2 Italians and Southern Europeans weren't considered whites (or at least not reliable whites), until the early 20th century only people from England, Scotland, Wales, Germany, Scandinavian countries and Benelux were considered "true whites". Also, don't forget the Hispanic/Latinos many them have white ancestry and are marrying white people and having white kids.
There's a lot of spics who are white-passing already. Many of them have spanish conquistador DNA, so they will go back to their roots anyway.
Germanic, aryans, scandinavians, irish, etc americans... Sorry... You will be replaced. Try to at least do something. Make the hispanics right wing, that's the least you can do.
