If you knew nothing of Scientology at all, the thing to do would be to
look at photographs of those who are afflicted. Start of with David
Miscavidge himself. You will see that he no longer looks like a human
being at all. There is so much calculation and trickery in the man
that he now appears rather less human than Data from Star Trek. The
skin of DM appears to be made of some PVC material and he has replaced
his personality with a series of routines designed to control others.
David Miscavidge no longer even exists and has become an embodiment of
the tech.
Tom Cruse is also well on this road. He also has this plastic inhuman
quality to him (see the infamous scientology video), but he can hide
it most of the time. Tom Cruse has fallen back upon his acting as a
substitute for being a human being..
Tom's loss of humanity may be the true reason for his hysterical
emoting on Opera. He can fake emotion (he is an actor) but can no
longer experience them. He therefore jumps up and down of a sofa
because he has no idea how normal people express emotion.
John Travolta was also a plastic person once. He is becoming more
human and I wish him well. I hope that Will Smith does not develop it,
but we shall see.
