Cryonauts as religious security risks

Just pure speculation on my part: What if the people in Future World would feel reluctant to revive cryonauts because they fear that at least some of us could inadvertently reintroduce religious beliefs that they consider undesirable or even dangerous?

How could this occur? People with fringe religious beliefs now generally don't pose much threat to our society unless they act upon them in ways which harm others, like radical Muslims, christian parents who let their children die from treatable diseases because they believe in faith healing, or Mormon polygynist men who "marry" 12-year-old girls. Religious obsessives like these examples generally haven't shown interest in cryonics.

Well, suppose that the people in Future World have a technology like the Krell Machine, but unlike the Krell in the movie Forbidden Planet, they've constructed a firewall to protect society from anyone using it to create something harmful, even unconsciously. (The movie uses Freud's psychoanalytic term "the Id" [das Es] to describe the refractory, unconscious part of the mind.) Their Krell Machine doesn't necessarily have to produce stuff; it could also generate software constructs as directed by the minds of the people in Future World.

The society in Future World might also have taken measures to control antisocial tendencies in the minds of its inhabitants based on a deep understanding of cognitive science, including measures to suppress the destructive aspects of religiosity. (If the worst manifestations of religiosity don't demonstrate "monsters from the Id," I don't know what does.) So they might not worry so much about the prospect that we would restore forms of religious belief and practice which have long since died out, because their minds would not suffer from that kind of susceptibility.

What could they worry about instead? Introduce into that society revived cryonauts who come from the era of "feral" human minds, and our monsters from the Id might find ways to breach the Krell Machine's firewall to create the religious equivalent of, say, the Stay Puft Marshmallow Man.

Of course, our resuscitators could revive us and put us in quarantine as well, with no access to the Krell Machine. If the Krell Machine becomes as necessary to making a living in Future World as the internet shows signs of becoming in our world, then we could find ourselves seriously disadvantaged, indeed, at least until Future World can find better ways to accommodate us, or we can find those ways ourselves. If we revive with radical life extension, we'll certainly have the time to work on this "interesting" problem.
