Don't have time to read the link, so I'm just going to shoot from the hip. Maybe he clarified in the article.
But, I think he's right. and, I am not saying "no more brown people in America", what I mean by that is you buy into our way of life and assimilate, or you should not be here. Sorry if reading the article would have said the same thing, I'm eating a McGriddle and have no time to red, only to type one handed...
