If you don't get your kids vaccinated in the UK in 2010, that's lousy parenting, but if absolutely everyone you ever meet thinks that vaccines are the work of the devil, then "lousy" seems too strong a term for going along with it.

True. However, if absolutely everyone you ever meet thinks vaccines are evil except for one doctor and that doctor has science on his side, and you choose not to get your kids vaccinated because of "going along with" social pressures, then "lousy parent" is exactly the right strength of term. And that's really the case here. Not absolutely everyone thinks cryonics is wrong or misguided. And if you can't sort the bullshit and wishful thinking from the science, then you're doing your child a disservice.
