To be aired this weekend in Ireland. Will post whole show link when available.
FWIW, I was deeply impressed with the integrity and sincerity of Mick Peelo (and his assistant, Bertha) who asked the difficult questions about how this entity could flourish in the Church in which he was raised. I hope the discussion over the cultishness of the Legion will be included in the show, because it's still the "elephant in the living room" that will not be discussed.
To clarify, the word "cult" is at the root of both cultivate and culture -- two very good things. The perniciousness of a cult within the legitimate cult of Catholicism (yes, "cult" is a healthy word in that sense: the cult of saints, the cult of Mary, etc.) is likened to a poisonous plant that attaches itself to a good plant: think kudzu in the American south.
Kudzu's environmental and ecological damage results from acting through "interference competition", meaning it out-competes other species for a resource. Kudzu competes with native flora for light, and acts to block their access to this vital resource by growing over them and shading them with their leaves. Plants may then die as a result, from being suffocated.
Don't let people throw your argument off-track because of the various uses of the word. We're speaking of the diagnostic manual's definition of high demand groups, which use psychological manipulation to draw and retain members. God willing, the RTE piece will touch on this dimension.
