Because there is a limited amount of free energy in the universe, you probably don't get revived in a bad future. A society that knew enough nanotech to revive you is one where you would not be a profitable slave or organ bank, and they are only likely to bring you back if they value your happiness. Also, there is some chance that you would be able to kill yourself post-revival if you found life worse than death.

Your dad might enjoy my book Singularity Rising which makes the case for cryonics in one chapter.

I don't know how to characterize the disgust that lots of women feel towards cryonics, other then to say it seems to fit comfortably in the "disgust" category of emotions.
