A number of US commenters have been hand-wringing about RFK Jr’s nomination. “He supports people being able to purchase raw milk, don’t you know!” “He wants to discourage municipal water plants from adding fluoride!” He is concerned that the “MMR vaccine is linked to autism.”As the media tries to portray RFK Jr as a conspiracy theorist, I think we need to draw a distinction. Some of his views are correct, others might be wrong, but worthy of debate, and yet others take things too far.As the Overton window shifts, we need guidance. My proposal is this: When you hear an RFK Jr idea, or the media discusses it, ask; Do other nations/ states or cities do it that way? If that is the case, then RFK is not, prima-facia, crazy. Let me be clear; that doesn’t mean he is right, but that does mean his view are not apocalyptical, and we should talk about it.
