I could care less what 'color' Americans are. What I don't want to see replaced is Americanism and American culture. I don't want to see America become like S. America or Western Europe, or even like Asian culture. America didn't become the nation it is by adopting any of those cultures, or other ones besides those. Instead, America created a unique culture that in many ways has made the world a far, far better place because of it.
Yet, the Left in America wants to destroy that culture and replace it with some half assed version of cultural failures that hail from Leftist politics. We can see where those have gone in other nations and yet, the Left in America argues for that same sort of failure here.
