I never thought of it that way, but hell to the yah!
Someone said that to me about 5 years ago; my only family member with whom I am secretly in touch. *grins* I get strong vibes that he has never really 'believed', and he said to me once, rather wistfully "But where would I go?"
And when I think of it, with a lifetime of being in the b'Org, marrying young, never 'readhing out' to be an MS, but faithfully attending and going in FS only the minimum, yeah, he doesn't believe. But it would be daunting to go out into the world, at 50+, and leave the KH (his spouse is a True Believer, as is most of the family), and all that you knew behind.
They truly do drill this scripture into our heads from birth (yes, we are born-in, my family), and by their isolation of the cult members, reinforce the very real fear of being alone in a world of scary, untrustworthy strangers.
This is not happifying.
