The recent arrests of the Hutaree cult here in Michigan are part of a tradition of militant separatism in this part of the country, beginning with the militia movements in the late 20th century and climaxing (hopefully) in the terrorist acts of Timothy McVeigh and Terry Nichols. This latest incident is interesting in that it appears to share some qualities of the militia movement, the Christian Identity movement, and the Tea Party movement (although what sorts of ideologic connections there really are will take some time to figure out.)
Cults in general scare me. They scare me not just because of their acts and their ideas, but their attractiveness. They have the ability not just to attract those of similar ideas, but they also seduce those who may simply be vulnerable to their philosophies. The flames of hatred are being fanned by those on the right, including teabaggers and so-called mainstream right wing commentators. The economic times, an "ethnic" president who represents the future of the US population, and an utter failure of others on the right to speak out against the hate feed these right-wing violence cults.
But cults don't just feed on hatred. Cults, like street gangs, also seduce with love, with pleasant-sounding ideas that are congruent with and confirm one's own beliefs. The antivaccine movement (as opposed to individuals with their individual beliefs) are a cult. They have charismatic leaders (such as Barbara Loe Fisher, JB Handley, and Jenny McCarthy), they have their own beliefs that are impervious to the assault of actual facts, and they accrue followers, spreading their lies. Their lies have helped to lower vaccination rates and increase the incidence of vaccine-preventable diseases. And their success depends upon a general cheapening of the meaning of "experts", and a vilification of earned scientific authority when it disagrees with their beliefs.
