Limbaugh goes for the white-nationalist gimmick:

Limbaugh: “Western Civilizations Are … Erasing Themselves” Through “Illegal Immigration, Normal Immigration”

LIMBAUGH: Do you know what the fastest growing language in the United States is? Nope. It’s Arabic. Fastest growing, not the most spoken. The fastest growing language in the United States is Arabic. Here’s another headline. World’s first lesbian bishop calls for church to remove crosses and to install Muslim prayer space instead. There is a creep, creep, creep, creep, creep that is happening throughout western nations, western cultures, and western civilization countries. It is a creep, creep, creep, creep, creep through various means: illegal immigration, normal immigration, intimidation, political correctness, what have you. But Western civilizations are pretty much in the process of erasing themselves, in my view anyway. The people who wish to erase Western civilization in many cases are not even firing a shot. Some are, such as ISIS and Al Qaeda and all that. But illegal immigrants are not firing a shot. La Raza is not firing a shot. Number of the domestic upheavals in this country are happening not because of any kind of force. They’re happening because of political correctness, fear, intimidation, you name it.

Besides the multi-dimensions of idiocy in there, one that stands out to me is the misunderstanding of what is “western civilization”.

Only in a medieval Papal view is the eastern Mediterranean not part of “the west”.

But a more accurate view of our past shows that the people on the east side of the Med and in North Africa are part of the course of western civilization.
