Let me explain, in case you never read your history, just what "The Protocols..." is.
The tract, as you can read on any link followed from the words 'anti-semitic bullshit' above, was produced in Czarist Russia by the Secret Police of the time, the Okhranka, to lay a foundation of blame on Russia's Jews for Russia's problems during it's Revolutionary era. The rise of National Socialism in Germany can be in part blamed on the circulation of the Protocols throughout Europe in the early 1900's.
This tract then, has influenced everything from the Krystallnacht to the rise of the Klan. It is the original paranoid conspiracy theory in a booklet purporting to outline the Jewish plan for world dominance.
I read the CNN piece I linked in the first sentence above the other day and thought maybe I was wrong - that it wasn't the same racist bullshit that at least one virulently anti-semitic member of my family once owned. Surely the all-American Wal-Mart chain would not play any part in the promotion or distribution of such a work, except as plainly labelled fiction, or perhaps for use as a study of the history of propaganda. Nope. They just sold it, along with the whole Left Behind Series, I'm sure.
How can one boycott Wal-Mart? They've done what they do brilliantly. You virtually have to go there. Yet that creeping sense of paranoia I've always felt about the giant corporation's encroachment on all suburban and even urban retail territories has now been magnified tenfold.
"The Protocols" has been dubbed, as the CNN article states, a "warrant for genocide." And it was being sold by America's most pervasive face of bland capitalism without their denial (or, to be fair, support,) of it's message.
