The Oklahoma City bombing accomplished by convicted murderers Timothy McVeigh and Terry Nichols, followed the plot of a bombing described by founder of the National Alliance William Pierce in his 1978 book "The Turner Diaries."
A conference in New York City convened by the American Jewish Committee examined the growth of organized hate groups within the United States.
Recent incidents that involved white supremacists included the so-called "Freemen" of Montana, who promoted violent racism and anti-Semitism.
Freeman Rodney Skurdal wrote: "The Bible is written for only one race of people . . . God's People, the white race." When white Christians " . . . move into a new land, we are to kill all of the inhabitants of the other races . . . nor are we to allow other races to rule over us."
Skurdal can be seen as one example of the growing Christian Identity movement, which uses religion to mask its hatred of blacks, Jews, homosexuals, and other supposedly "inferior" peoples.
Law authorities have said that Eric Rudolph, wanted as suspect for the January 1998 fatal bombing of a Birmingham, Alabama abortion clinic, was influenced by Christian Identity.
Official estimates have stated there are 16 Christian Identity groups in Missouri and three in Kansas.
John Trochman, a founder of the so-called "Montana Militia," warns that a "world government" will soon take over the US. The UN plays a pivotal role in Trochman's paranoid conspiracy theories, which include ominous black helicopters.
Richard Butler, a neo-Nazi and leader of the Aryan Nations talks about "eliminating Jewry" and is devoted to the memory of Adolph Hitler and the Nazis.
Before the Oklahoma City bombing most Americans ignored hatemongers like Pierce, Skurdal, Trochmann, and Butler. They were often dismissed as "kooks" or "crazies." But since that tragedy that claimed 168 lives attitudes have changed.
Many hate groups preach a seemingly pathological distrust of the federal government and civil authorities.
One law enforcement representative speaking at the conference said, "It's really dangerous when you start mixing guns with religious beliefs that are far to the right."
