I'm trying to say that I think you might already be a pretty extreme outlier in your opinion of cryonics, based on a few clues I noticed in your comment, so your reactions may not generalize much. The median reaction to cryonics seems to be disgust and anger, rather than just not being convinced. I'm sort of on the fence about it myself, although I will try to refute bad cryonics-related arguments when I see them, so on object-level grounds I can't really say whether convincing you or learning how to convince people in general is a good idea or not.
Disgust and anger, that's interesting. I wonder if that might be due to them feeling it's unfair that some people might survive when everyone else has died, or seeing it as some kind of insult to their religion like trying to evade hell (with the implication that you won't be motivated enough to avoid sinning, for instance). If that's the case, you're probably right that my current reaction is different from the ones that others would have. My initial reaction was pretty similar, though. My introduction to cryo was in a cartoon as a child - the bad guy...
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
