Not all Web publishers listed by Goldman are willing to accept being labeled as hate groups.

Mike Alamore, minister of Kingdom Identity Ministries, which describes itself as a "Politically Incorrect Christian Identity outreach ministry to God's chosen race (true Israel, the white, European peoples)", calls the categorization "unfair."

I'm not the only person or group that's been called names," he says.

The Holocaust denial category is particularly problematic. While some sites express hatred for Jews, not all do.

Arthur R. Butz, associate professor of electrical and computer engineering at Northwestern University, runs a Web site on the university's server dedicated to Holocaust revisionism.

"This is historical revisionism of a sort," he says. "Just about any history project worth anything is."

He maintains that his opinions are not hate speech but says he is "not terribly upset" about his listing on Hatewatch.

"I'm accustomed to observing a lot of stupid people commenting on this," he says.

But Ganz says the ADL considers Holocaust denial with or without explicit anti-Semitism to be hate.

"Holocaust denial is an aspect of anti-Semitism," she says. "You cannot have a site that says that the Holocaust didn't happen or didn't happen the way history shows it happened without considering it anti-Semitism."

Potok says Klanwatch also sees the close relationship between Holocaust denial and anti-Semitism.

"By and large it is a cloak for anti-Semitism," he says. "The far right by and large has taken great pains to strip away explicit racism and couch arguments in pseudo-academic terms. They don't talk much about satanic Jewish bankers running the world but that is the subtext."

But while Hatewatch lists Louis Farrakhan's Nation of Islam site under the category of black racism, Potok says Klanwatch has not listed the organization, though it does monitor it.

"It's not clear that all members of the group fit into the category of a hate group," he says.

He notes, though, that the president of the Southern Poverty Law Group recently called Farrakhan a "notorious bigot" in a newsletter.
