Though no one has mentioned it here and I haven't read the book,
surely a central point in Buchanan's book must be that for over two decades import quotas from third-world countries have far exceeded those from first-world. People from third-world countries tend to have cultural traditions radically different from our own, but those from the first-world tend to be very similar culturally.
I'll wager the book is far more about culture than about race, but if one wants to raise straw men and red herrings race is always a convenient vehicle.
You are exactly right. Pat's book is a lament on the death of western culture, not the white race. It happens that that the carriers of that culture happen to be white. Anyone who doubts that we are heading for some kind of slow-motion cultural / demographic civil war in this country hasn't visited California or southern Texas lately.
I'll wager the book is far more about culture than about race, but if one wants to raise straw men and red herrings race is always a convenient vehicle. Exactly. Can we not accept that to speak about culture is also to speak about race? Can you, Sink, separate the two?
