Enrolling in a Job Corps training programme in Salt Lake City in the 1970s, Kaldenberg became "aware of racial realities" after having fights with blacks and Muslims.
White Aryan Resistance
In the early 1970s Kaldenberg joined Tom Metzger’s White Aryan Resistance. He was the managing editor of their paper WAR:178 until 1989 and Metzger's bodyguard.
In October 1990, the Southern Poverty Law Center and the Anti-Defamation League won a civil judgement against Metzger and WAR on behalf of the family of Mulugeta Seraw, who was murdered by white power skinheads associated with the group. Metzger then encouraged his supporters to send donations to Kaldenberg rather than to him or to WAR, in order to avoid paying the judgement. Kaldenberg was the subject of a court order freezing his funds, pending court review. In January 1991, Kaldenberg began withdrawing money from the frozen account just hours after the order was issued. He was ordered by a San Diego municipal judge to return it. Kaldenberg refused to obey the order and was jailed for 10 days for contempt of court.
Kaldenberg was briefly involved with Stephen A. McNallen's Ásatrú Free Assembly but left when McNallen ejected Nazis from that organization. Kaldenberg and other "Aryanists" who left the AFA at that time went on to found the Greater Los Angeles area chapter of the Odinist Fellowship.
After leaving the AFA, Kaldenberg developed a distinct variety of Odinism. He devalues spirituality and ceremony and rejects Judeo-Christianity. According to Nicholas Goodrick-Clarke, Kaldenberg's version of the ideology is "chiefly a cult of aristocracy, power and the propagation of the white race."
Kaldenberg began publishing Pagan Review in the 1990s which was described as "a voice of Eurocentric polytheistic communities."
