I have signed up with Alcor. When I suggest to other people that they should sign up the common response has been that they wouldn't want to be brought back to life after they died.

I don't understand this response. I'm almost certain that if most of these people found out they had cancer and would die unless they got a treatment and (1) with the treatment they would have only a 20% chance of survival, (2) the treatment would be very painful, (3) the treatment would be very expensive, and (4) if the treatment worked they would be unhealthy for the rest of their lives; then almost all of these cryonics rejectors would take the treatment.

One of the primary cost of cryonics is the "you seem insane tax" one has to pay if people find out you have signed up. Posts like this will hopefully reduce the cryonics insanity tax.
