I don't see the video and its message as facile at all. Dissecting its teachings and approaches are necessary to uncover its harmful effects on the lives of those touched by it.
The number of threads or comments about the video is hardly overkill. Lurkers and posters probably don't enter every thread. Therefore, if someone wants to comment on a topic, they may post on an existing thread or simply start their own (such as yourself) instead of wading through previous threads. It may be that simple.
I ain't no amputated limb either... ouch!
