Immigration and Racism

"It is perfectly true that our present immigration policy does (and should) favor North Europeans over people from other parts of Europe, while it discriminates still more rigidly against the entry of non-white races. But the basic reason for this is not a theory of race superiority, but that most fundamental and most legitimate of all human instincts, self-preservation — rightly termed 'the first law of nature.'" 

~Lothrop Stoddard
