Caldwell just now noticed that?
This is the reason Buchanan writes his books.
Stir up the faithful (just look at how many Buchanan threads we've seen in the last month), then others want to see what the pitchforkers are squealing about.
Buchanan loves a fight. Every book he's ever written has provoked one.
He may believe what he writes, but he knows how to use hyperbole and touch all the right symbols (the Confederacy, "whiteness," "Western culture").
IOW, he's a book publisher's dream.
