Okay I'm being cheap and not reading all the posts, but there is a small point I'm going to make that is a programmatic equation:
Say it takes two Parents of differing DNA code to make a unique individual, by evolution standards this is the best course because of the blending that occurs.
Now take the raeliens version, one parent giving birth to it's own clone, no evolutionary changes in the DNA other than perhaps a virus or cold structure.
It would actually bring about the demise of mankind IF utilised to generate new generations because nobody would mutate any antibodies to disease.
If the Raelians truly had an alien talk to them and convince them of the cloning antics, it would probably be to wipe them out from a strategic point of view. (although this gets as beyond science as they do)
On a personal note, I don't think the Raelians should class themselves as a religion purely because they didn't balance the ethical dilemas that other religions would have seen.
So I would most definitely call it a crackpot cult.
