The pervasiveness and pejorative aspect of Holocaustery is eloquently demonstrated in this post on the Web site of The Occidental Observer (TOO).
TOO is a "white nationalist" organization, and its overtly racial principles expose it to accusations of Neo-Nazism with a frequency that might exceed even the frequency with which the charge is leveled at CODOH, which does not advocate for or against any race, religion, party, or group.
In "Strategies for White Advocacy," the section headed "Avoid the tripwires of massive propaganda" begins with the stringent advice never, ever to mention or betray the slightest sympathy for, or even interest, in "Holocaust revisionism." I'd guess the danger lies in the direction of the Neo-Nazi charges they'd understandably prefer to avoid.
But the testimony to the power and wrath of the Holocaust mythology is stark, in and of itself.
