As one who came out of CZ - 20 years - I think I know something about it. However, CZ is not the culprit directly - it is the rest of Christianity which turned into Churchianity, and thus lost its mission which Jesus gave it in Matthew 28:18-20.
It's a bit of a long story, but my website - www.crushlimbraw.com - begins to tie all the loose ends of this Christian conundrum.
In essence, the church at large defaulted to humanism and lost its zeal - thus the resultant siren song of CZ became very appealing to any Christian looking for a more zealous practice of worship - but still deceived!
Read and decide for yourself - but a warning - this is not for casual readers or short attention spans.
