Scientology is a package deal as created by Hubbard imo. Perhaps some useful things could be surgically extracted from the rest of the crap to benefit people. But then it is no longer Scientology. One can't just pick and choose those things with which he agrees with and say that that is "Scientology". Even if you tried to do that you'd have students who "discovered" the censored writings of Hubbard, including KSW, and begin following those policies. Hubbard made it pretty clear that NOBODY had the ability (other than himself) to cancel or alter in any way KSW Series#1. And THAT policy is responsible for much of the insanity and fanaticism caused by Scientology.
The Scn philosophy is deeply embedded within the Ethics Tech and Hubbard made it pretty clear that one cannot get Tech in until Ethics was in.
One cannot seperate the philosophy from the Tech, and the philosophy has much to do with the abuses (as Auditor'sToad previously mentioned).
By the way, wasn't KSW Series#1 issued as both a bulletin (red on white) as well as a policy?
