Here's an interesting article about the relatively small but rapidly growing numbers of radical traditionalist 'Catholics' who subscribe to regressive, pre-Vatican II doctrines and rituals that include virulent anti-Semitism and a preoccupation with conspiracy theories that would rival those of any Grand Dragon of the KKK. Often referred to as a Catholic, Mel Gibson is actually a member of such a sect that operates from a church that is closed to the public and entirely funded by Mel Gibson.
Although these extremist sects operate without the approval of the Vatican, I wonder about the extent to which the previous Pope bears some responsibility for this trend. JPII's personal affinity with and support for fetishized Catholicism can be seen among the burgeoning traditionalist religious orders and societies that have been operating within the Catholic Church in recent years. Though they would disavow anti-Semitism, these Vatican approved societies share many similarities with the radical traditional sects including their fetishization of the Virgin Mary, the Latin Mass, ritualism, adoration of the host and, in some cases, ritual self-abuse for the expiation of sin.
