| Careful with qualifiers there. I genuinely believe that vaccines can spread illness to the non-vaccinated, since it has happened many times and is well-documented. For example, it's why only the inactivated (aka "dead" virus) polio vaccine has been used in the US since 2000. I'm not arguing about whether the risks of the attenuated virus outweigh the benefits. I think the data are very clear there. (Heh -- and I'm sure the vast majority of people will agree with that statement, even if they disagree on what the clear answer is....) It's just that one shouldn't mock a belief without including the necessary qualifiers, as otherwise you're setting up an argument that can be invalidated by being shown to be factually incorrect. As for genetic modification of humans, IMO there are a lot of very good reasons to be wary, most of them social. Fatal hereditary conditions are obviously an easy call. What about autism (not saying there's a genetic link there to use, just a what if)? Or other neurodivergence? Like being a troublemaker in class? Or voting for the party that doesn't control the medical incentive structure? Heck, let's stick with the fatal hereditary conditions, and say the editing does not affect germ cells. Is it ok if the human race gradually becomes dependent on gene editing to produce viable offspring? Or let's say it does extend to germ cells. The population with resources becomes genetically superior (eg in the sense of natural lifespan and lower medical costs) to those without, creating a solid scientific rationale for eugenics. Think of it as redlining carved into our blood. I don't think discrimination against the genetically modified is the only potential problem here. As humans, we'll deal with these problems the way we've dealt with everything else transformational. Namely: very, very badly. |
